So I was watching the news and they did a small blurb about that Waco biker shooting hootnaney. It piqued my interests so I turned the sound up. After it showed a gentleman vigorously hosing away what I would imagine was some sort of bodily fluid it cut to the police chief of Waco. (I'm paraphrasing here) He said they found "Assault knives" and guns all sorts of guns, handguns blah blah "the largest caliber gun we found was an AK-47". Anyways, I always used the term "assault knife" in jest. According to this guy it must be a real thing. So the question is: is Assault knife a valid term or definable object or is this a politically pandering idiot who is just flappin' gums?
