I do not understand that part of this whole thing.
If the drugs were planted, that would make more sense, because I can't imagine anyone doing a video like he did (which he had to have known would prompt some kind arrest) and not having removed any kind of drugs (if he had them at all) prior to any "event" coming down.
I mean, THAT would make NO SENSE AT ALL.
So, I hope he wasn't careless, because if he was, I would think he wanted to go to jail. And, the idea he's sitting "mum" is amazing to me. That's not something most of us would do. I know I wouldn't.
