The overwhelming majority of legal gun owners are not people I’m afraid about. In the world you you’re suggesting, the illegal guns would still be out there. Nothing would have changed it that regard.

As for weed, I very rarely made strictly marijuana possession arrests. The right to marijuana also isn’t in the bill of rights. Weed was always an easy way to search a car looking for something else like illegal guns. Personally, I think most drugs should be legal, but that’s a different discussion.
