Technology needs to be treated in a similar manner to finance. There are specialist judges, barristers etc. whose expertise is utilised in such cases. They do not need to be experts in every minutiae, however, they know a significant amount that they can be brought up to speed (often by themselves) on a specific issue.
Currently computing in law is being treated as a physical science where they roll out an expert and expect them to explain the specific relevance.
The difference is that, just like finance (i.e. in fraud cases), computing IS the case whereas more often than not physical science is JUST A POINT in the case (albeit important).
