I found the following article linked from my BCS newsletter to be quite interesting:

http://www.bcs.org/server.php?show=nav.8280

It gives quite a well written, interesting guide to digital forensics, from preserving the "crime scene", to presenting digital evidence in court and the methods use to examine a computer seized by forensic experts. It also looks at the way people try to cover their tracks and asks whether our laws are adequate to make sure criminals don't go free.

Better than the usual semi interesting stuff that BCS send me links to at any rate!
