I assume you mean clinical forensic psych? I really know of no such videos and doubt one exists really, as this is is an enormous issue with a million possible topics. However, I think you must have a good understand of the ethics code first, because alot of the issues you will be dealing with is where the APA ethics code comes into conflict with specific state/federal laws, case law, rulings from the bench, etc.
There are several good books on the matter I'm sure. Glen Larabee writes extensively about forensic neuropsych and the ethics of forensic neuropsych assessments. See what pops up on amazon.
