But some judges are pretty good...
The truth is judicial competence in IT matters is patchy not wholly absent, and it is difficult to predict, from judge to judge, what will happen in trial.
But to redress the balance of this particular news item and based on my not infrequent appearances as expert witness:
* a judge in the relatively sleepy market town of Aylesbury was fully up-to-speed with how peer-to-peer file sharing works
* in the recent defamation case between WPP's Martin Sorrell and former Italian business partners, the judge was able to cope with blogs, onion-routing and other anonymising techniques and the contents of registries as found in Windows recovery points. (and his normal territory includes privacy squabbles involving celebrity magazines)
* the district judge in the "pen-tester hacked into charity web-site" case had to understand web-servers, intrusion detection system logs and directory traversal hacks in deciding whether the Computer Misuse Act had been broken.
* at least one member of the Judicial Committee of the House of Lords is an enthusiast of flight simulators on the PC
Usually the authorities assign appropriate judges to cases which involve computer-derived evidence, though obviously not in this case. But at least part of the resolution of the problem relies on the skills of lawyers and, erhem, expert witnesses
