towards the evidence generated by, or about the behaviour of, computers in cases they consider.<br>

She refers to Paul Marshall's masterful account to the University of Law of the PO Horizon affair <br>

<br>
Susan also singles out Paul's observation that ".... writing on a bit of paper in evidence is only <br>
marks on a piece of paper until first, someone explains what it means and, second, if it is a <br>
statement of fact, someone proves the truth of that fact."  This applies strongly also to arguments <br>
presented in assurance cases for safety-critical systems.<br>
<br>
Rather than say more here, I refer to my blog post <br>
