1) Learn what the hell an assault weapon is. Assault weapon = select fire. Just touching an illegal one on TV would have the ATF so far up your ass you wouldnt know whether to spit or swallow. Exactly one crime has been committed since the early '90s with a real live machine gun, and they got it from Mexico. The TV people like to say "assault weapon" when it suits their purposes.
2) 20/20 has been established so far in this thread as a hotbed of well checked and factual information. From one of my posts on the original topic of the thread, "ABC's "20/20" aired a particularly ignorant "report" the night after the tragedy, linking the killers to the scene with alarmist messages about Satanism and cults."

You can drive trucks through the factual loopholes in their reporting.
