Re: Statutory inquiry
"Why did judges not know about software evaluation, CHECK or CREST certified technical testing of software, how System Administrators manage user accounts and query the PO lawyers on them?"
These were, or should have been, facts brought to the attention of the juries. It is the juries who determine facts, not judges although the latter do sum up the evidence for the jury as well as acting as referees in terms of application of the law.
The juries (and, for that matter, judges) didn't know because they were not resented with evidence of it.
