I think it's fine that JG has a lawyer to advise him through this process. His name did come up, or was injected into the investigation. There may be more to come, from outright accusations to attempts to romp through his phone records, etc. to try to come up with some reasonable doubt for the defendant. A number of the people sought to be subpoenaed may protest and may have to do so in court. Tim from TES certainly benefited from having a good lawyer help him when all his records were sought in a fishing expedition.
Painter, my friend, I didn't mean to sound so sinister before! These people aren't going anywhere. I'd just see what develops (Oprah interviews, etc.), be prepared and decide later.
