    "Perhaps it is now the health service and the justice system that should
    be on trial." reads the front page headline of the Daily Telegraph,

    A few days ago I was listening to Archive on 4, Bombers, a look back at
    Chris Mullins' investigation of the miscarriages of justice regarding
    the Guilford and Birmingham pub bombings (https://www.bbc.co.uk/programmes/m0023pc7) where the programme
    questions whether similar interests shaped the scandal around the Post
    office Horizon trials. I wonder whether a future retrospective of the
    Post Office Horizon scandal will reference the trials of Lucy Letby as
    part of the the same?

    Well I'm not a lawyer and I'm not anti-lawyer, indeed I've known quite a
    few lawyers over the years and they were mostly admirable folk. But I
    have to say that I've been extremely disappointed by the defence teams
    in all of these trials.

    In the Letby cases, there are issues now being raised in which medical
    experts seem to say that few or perhaps none of the deaths show signs of murder. It is surprising that none of these experts were consulted
    earlier. The statistical evidence also seems, to a lay observer, a bit
    dodgy, and it is also surprising that no statistician gave evidence for
    the defence. It might not have made a difference, and I still have no
    idea whether Letby was guilty or not, but it seems to me that the trial
    process was rather unsatisfactory.

    In the Horizon scandal one can be sure that everyone who has ever
    programmed a computer will have been saying emphatically that one should
    never trust the output of a computer system, especially a complex one
    like this, as these systems are programmed by humans and humans make
    mistakes. It is astonishing that none of what must have been dozens or
    even hundreds of lawyers in the defence teams made any serious attempt
    to access the bug reports of the Horizon system. As soon as they were revealed, the scandal broke.

    The reason for that apparently, the absence of any robust defence,
    according to interviews with Letby's parents at least - was because all
    of them, Letby in particular, believed

    * she had no real case to answer * **

    Which, when looking over the actual "evidence" presented to the Court
    is not actually that far from the truth. The case against her was
    only ever circumstantial, and even that has been chipped way; alongside
    pure conjecture based on questionable theories from one supposed
    expert "witness"; who himself had decided which cases should be
    brought before the Court

    This is why Letby herself decided to give evidence on her own behalf;
    something she wasn't obliged to do.

    Not realising, that with their already having listemed to the farrago
    of supposition and half truths presented by the prosecution, when it
    came to her turn in the witness box, she would have little or any
    chance of convincing the jury of her innocence, no matter what
    she said. Over, as it turned out 60 hours of relentless cross
    examination.

    The fact that following her conviction, the Criminal Justice System
    including the Police, who brought her to "justice", have been falling
    over themselves to copper-bottom her guilt should comes as no real
    surprise to anyone. As their first loyalty will always be to
    the institution, themselves, rather than to any unfortunates who
    forgot to play by their rules. If only so as to protect the Greater
    Good.

    We may never know whether the lawyers who acted for Letby and acted for

    extremely difficult - lawyers aren't really better informed than laymen.
    They know a few experts who seem useful for specific cases. They put a
    lot of reliance on the "duty of care" of experts in court which is to be objective, non-partisan, point out any contrary viewpoints known to them
    and explain why they believe the contrary viewpoints are not valid. If a
    well respected expert gives evidence for the prosecution there won't be
    an assumption that he/she is a hired gun who supports whichever side
    pays him/her.

    Plainly Letby had to persuade the jury that there were explanations
    other than deliberate attacks on the babies. She was not qualified to do
    that detective work. And I don't believe that money had anything to do
    with it. Whether the defendant is rich or poor, they will get much the
    same representation from the criminal bar.

    And what will Lady Justice Thirlwall do? Complete her inquiry on the
    basis that Letby is undoubtedly guilty? Or pause or abandon the inquiry?
    The former is more likely.

    that

    of them, Letby in particular, believed

    * she had no real case to answer * **

    A gamble by the defence lawyers that failed dismally.

    Counsel are obliged to follow the instructions given by their client.

    Fortunate or unfortunate as that may be, in the terms of professional ethics.

    Letby's family are on record as being absolutley shocked by the verdict.

    The decision needs to be viewed from the possible perspective that

    * Letby knew all along that she was totally innocent *

    As far as she was concerned, she was innocent until proven guilty.

    And that all the suppositions and guesswork evident the prosecution
    case, as presented to the defence beforehand, were clearly a load
    of baloney; which would be blown to smithereens in Myers' cross
    examination of Evans, in the witness box.

    And as has subsequently turned out, Evans evidence was indeed a
    load of old tosh. Except that he made a compelling witness in the
    box. Best leave it that.

    However - once the jury believed Evans there was no point in calling
    further expert witnesses for the defence unless they directly addressed
    Evans claims. Which they apparently wouldn't have done.

    To repeat. It was for the prosecution to prove Letby's guilt. Not for
    Letby to prove her innocence.

    Which can possibly take on an entirely different perspective when a person
    * really is totally innocent*.

    More Letby misinformation. This from Gaby Hinsliff, in the "Guardian"

    A seemingly damning observation -

    quote:

    the death rate plummeted when she was, at colleagues' insistence, removed
    from the ward.

    uquote

    https://www.theguardian.com/commentisfree/2025/feb/06/lucy-letby-convictions-upheld-health-law-public

    Whereas in fact, as is widely known

    quote

    After further deaths in late June 2016, Letby was removed from neonatal duty. Around the same time,the hospital management downgraded the unit, so that it stopped
    taking the most premature babies with the highest risk of mortality. The number of
    deaths fell thereafter.

    unquote

    https://www.theguardian.com/uk-news/article/2024/jul/09/lucy-letby-evidence-experts-question

    Such a pity Gaby Hinsliff can't even be bothered to read up the background as provided by her own employer, before pontificating.

    never trust the output of a computer system, especially a complex one
    like this, as these systems are programmed by humans and humans make

    even hundreds of lawyers in the defence teams made any serious attempt
    to access the bug reports of the Horizon system. As soon as they were
    revealed, the scandal broke.


    At the risk of going off topic, can anybody offer an explanation of why the Horizon system ‘picked’ on certain sub postmasters (or some of them significantly more than others).

    But did it pick on some more than others? I suppose there must be
    detailed reports that would explain this, maybe even on the Inquiry website.

    What we do know is that the Post Office assured the sub postmasters that
    nobody could go into their system and interfere with the data that they
    had inputted, which was a lie because actually the Fujitsu people troubleshooting the software did, sometimes, go in and fiddle with the
    figures to make them look right. But this would not, presumably, be
    targeted at specific individuals.

    It is quite likely that some sub postmasters faced with a discrepancy
    and unsure of their skills with the software simply accepted that a few
    hundred pounds or a thousand pounds here or there must be owed by them,
    and they made up the shortfall and felt rather ashamed at having somehow
    got it wrong.



    You would have thought bugs would affect all branches similarly unless
    there was something in the transaction types, names or other attributes
    that it was processing.

    I’m not suggesting at all that they are guilty, but having designed and built complex computer systems, the manifestation of this seems extraordinary.

    As an additional observation, whilst all computer engineers believe that
    bugs are everywhere, many have extraordinary levels of confidence in their (bit of) software.

    But do they really? Or do they see that the system is flawed and needs expensive re-designing but their employer or client prefers that they
    just do what they can to troubleshoot and keep the system going?

    No, I would not think that. But even if you did, it would hardly seem surprising if it turned out that different post offices had different transaction type ratios.

    I’m not suggesting at all that they are guilty, but having designed and built complex computer systems, the manifestation of this seems extraordinary.

    You've built such systems and you still think as above? The mind boggles.
    It's the exact opposite opinion that I would expect from anyone with
    extensive programming experience.

    One of the faults, for example, was that when the sub-postmaster scanned
    in bags of cash received from HQ, if they clicked 'back' to double-check
    the figures then the system would silently record that twice as much had
    been received (or three times, if they clicked 'back' again, etc). So a
    more cautious or less computer-confident sub-postmaster who was more
    likely to double-check things was more likely to be a victim of the bug.

    Well I'm not a lawyer and I'm not anti-lawyer, indeed I've known quite a >>> few lawyers over the years and they were mostly admirable folk. But I
    have to say that I've been extremely disappointed by the defence teams
    in all of these trials.

    In the Letby cases, there are issues now being raised in which medical
    experts seem to say that few or perhaps none of the deaths show signs of >>> murder. It is surprising that none of these experts were consulted
    earlier. The statistical evidence also seems, to a lay observer, a bit
    dodgy, and it is also surprising that no statistician gave evidence for
    the defence. It might not have made a difference, and I still have no
    idea whether Letby was guilty or not, but it seems to me that the trial
    process was rather unsatisfactory.

    In the Horizon scandal one can be sure that everyone who has ever
    programmed a computer will have been saying emphatically that one should >>> never trust the output of a computer system, especially a complex one
    like this, as these systems are programmed by humans and humans make
    mistakes. It is astonishing that none of what must have been dozens or
    even hundreds of lawyers in the defence teams made any serious attempt
    to access the bug reports of the Horizon system. As soon as they were
    revealed, the scandal broke.


    At the risk of going off topic, can anybody offer an explanation of why the >> Horizon system ‘picked’ on certain sub postmasters (or some of them
    significantly more than others).

    But did it pick on some more than others? I suppose there must be
    detailed reports that would explain this, maybe even on the Inquiry website.

    What we do know is that the Post Office assured the sub postmasters that nobody could go into their system and interfere with the data that they
    had inputted, which was a lie because actually the Fujitsu people troubleshooting the software did, sometimes, go in and fiddle with the figures to make them look right. But this would not, presumably, be
    targeted at specific individuals.

    It is quite likely that some sub postmasters faced with a discrepancy
    and unsure of their skills with the software simply accepted that a few hundred pounds or a thousand pounds here or there must be owed by them,
    and they made up the shortfall and felt rather ashamed at having somehow
    got it wrong.



    You would have thought bugs would affect all branches similarly unless
    there was something in the transaction types, names or other attributes
    that it was processing.

    I’m not suggesting at all that they are guilty, but having designed and
    built complex computer systems, the manifestation of this seems
    extraordinary.

    As an additional observation, whilst all computer engineers believe that
    bugs are everywhere, many have extraordinary levels of confidence in their >> (bit of) software.

    But do they really? Or do they see that the system is flawed and needs expensive re-designing but their employer or client prefers that they
    just do what they can to troubleshoot and keep the system going?

    KTLO (keep the lights on) is a term I have come across for business
    critical systems where management has been seduced by the idea that some
    new system implemented with the currently fashionable technology will soon replace it. It means that only the most critical bugs get fixed and no resources are allocated to other improvements.

    All too often the wonderful new system works just enough for a shiny demo
    but lacks features or robustness needed to put it into service as a
    replacement for the old system. It may be brought into service to handle
    some of the work but that just leaves the software team with more systems,
    more code and more technologies to maintain.

    As for a system picking on a subset of the users it may be that there is
    some pattern of activity that triggers the bug. Starting from the
    assumption that the software is flawless, any attempt to see whether or not that is the case will be shut down before it gets off the ground. Tracking
    down bugs that affect only a few people and only some of the time requires
    the more skilled and experienced software engineers but they are needed to
    work on the urgent task of rebranding to show the new corporate logo.

    Well I'm not an expert but have designed and used a number of database
    systems and read a bit about Horizon (though very little has been made
    public).

    Pretty much all database management systems have facilities for
    declaring a group of operations to be done as a single unit, often
    called a transaction, so that all succeed or all fail together.
    Typically in a transaction one operation might debit an account, then
    another credits the same amount to another account, thus doing a
    transfer. At the end of the transaction, if something goes wrong the
    system can roll everything back to the start of the transaction and thus
    unwind all the partial transfers. One can then try again, or not, as
    seems appropriate.

    The designers of the Horizon system deliberately, or perhaps through
    ignorance, did NOT use that technique. Personally I think this makes
    them very much to blame for the whole sorry mess.

    This omission was compounded by the fact that the sub-POs were connected
    to the central servers by telephone lines of varying speeds and
    reliability. I suspect that some sub-postmasters, finding that some
    operation was hanging would simply click the button again. In some
    cases this would let some transfers go through but not others which
    should have been linked to them as part of a single transaction,
    resulting at the end of the day in a monetary imbalance. Other
    sub-postmasters might have been more patient, or have had better comms
    links, or just been lucky. This is my guess why some branches appear to
    have been much more badly affected than others.

    If my guess is right then a great many branches will have been affected somewhat, but many of them by small imbalances which they probably
    thought were their fault, or perhaps were not worth complaining about.
    After all we know what often happened when they did complain: the
    actions of the supervisors and help staff often made things worse.
    And some of them might have got errors in their favour some of the time
    - which they might well have kept quiet about.

    No, I would not think that. But even if you did, it would hardly seem surprising if it turned out that different post offices had different transaction type ratios.

    I’m not suggesting at all that they are guilty, but having designed and
    built complex computer systems, the manifestation of this seems

    You've built such systems and you still think as above? The mind boggles. It's the exact opposite opinion that I would expect from anyone with extensive programming experience.

    One of the faults, for example, was that when the sub-postmaster scanned
    in bags of cash received from HQ, if they clicked 'back' to double-check
    the figures then the system would silently record that twice as much had
    been received (or three times, if they clicked 'back' again, etc). So a
    more cautious or less computer-confident sub-postmaster who was more
    likely to double-check things was more likely to be a victim of the bug.

    Thank you (genuinely).

    That explains a lot.
