I don't know any dealers that do their own haul in bulk, those are the ones asking to be busted. They carry what they are going to sell and re-stock to avoid a heavy charge if they get picked up. Any dealer dropping off ounces and more would be a moron to be holding more than he needs. As far as your second point, I agree with dubadegi more, he had no tools for consumption, such as papers, blunts, pipes, etc. But he did have a scale. That is distribution tool. I'm not saying he intended to distribute, but let's say it's a cop pulled him over and had no idea who he was... the signs point more toward distribution than consumption if you look objectively at the evidence.
^ ... This is the first I heard of a scale involved - i see that he edited his original post at some point to include that. If that's the case than this devils advocate play has been pointless. Bottom line is that this guy was a jackassasaur in some way or another.

Let's hypothetically say this is Bastard Father, I wonder what the disciplinary action would be. Likely a pay raise......
