What level of qualification would be required for a computer expert to testify about linking the IP of a computer to posts on a message board? Is a graduate degree and publications required? Or have the courts taken to accepting lesser qualifications or even dispensed with the requirement of expert testimony for linking IP addresses to computers?
Would the qualifications be different in a civil trial versus a criminal trial? I.e., would a police computer forensics expert require different qualifications than a civil expert?
