And you dont know why? It's cos he's still a baby... Children get arrested immediatly. ADULTS dont get arrested unless they got alot on them.

An adult can get away with about a 1/4

And yes, the police DO need a search warrant, but as far as i can remember from what happened with me they are allowed to come in, just not search... So if you got a kilo on your living room table and they see they can take it and arrest you instantly.
