I did not mean to train them to make them technology gurues, no. But they have to know at least the basices of technology and what it can afford to the court...

An example:

Lawyer: Mr.Judge, the accused person was in NY city at the same time of the crime {Washington DC}?
Judge: How come?
Lawyer: We found out that the accused has sent an e-mail to his brother in England, after tracing the IP you come up that he was not in Washington DC.
Judge {Unconvinced}: The person is pleaded guilty.

This would happen if the judge don't know that IPs may indicate the place of the person, on the other hand he also must also know that it could happen that some one may manipulate with their IP....
