The "assault rifle" in question was(per news source)not an automatic weapon so regardless of whether it was a pistol or not would have to have pulled the trigger 50 times for 50 shots.

If you don't know that you are ignorant no amount of posting ludicrous reasoning will make you any more intelligent. There are no need for 500bhp vehicles either yet people keep buying them and more folks are killed in auto accidents in the U.S. than all firearms totaled. So why aren't you ranting about that? Stupid????
