Big thanks to Phuck Politics for sending me this link. What does this have to do with legal gun owners? Nothing directly, but indirectly, everything. Guns, like the one in this video, generally start out legal and through various means pass into criminal hands. The attitude and efforts of legal gun owners, along with that of manufacturers and dealers, is responsible for that.
After viewing this one, I'll bet our gun enthusiast friends will suggest banning skateboards.
