Rogue Pickpocket Skill (Looking for definitive ruling)

[evilkorn]

You can probably make a case for ninja looting if he's not in the group, but there is no proof that anything was picked other than the rogues screen. If he is in the group and didn't tell you he's picking, then he's a dick. If you see a failed message from the mob and tell him to stop then see it again, just boot him from the group.
