There was gentleman in California who was killed when his house was raided on "suspicion" of growing pot. It was discovered later that he was raided because it was hoped that his considerable property could be confiscated by law enforecement and he had just married a young lady who had once been arrested for having pot on her person.
He was killed by the officers conducting the raid because he was woken up and reached for a gun, a legally registered gun, thinking that his house was being broken into.
As it turned out, there was no pot being grown and there was none to be found.
Maybe. I don't know. As a libertarian it wouldn't particularly bother me if he did. But depending upon which state you are in you don't have to actually sell pot to get property seized.
