If Americans want to carry arms to defend themselves then fair enough, a hand gun maybe, still mad but there you go.
But how can anyone be allowed such heavy weaponry, even soldiers on the front lines in conflicts are not this well armed. It cant be self defence, it cant be shooting practice, cant be hunting. Its too powerful for anything logical, how can this be sold without questions.
Also, hundreds between dead and injured and people are questioning if its terrorism? really.
