You might be younger than me ^_^, but in my lifetime two legally civilian owned automatic weapons were used in crimes, both murders as I remember, one by a policeman, though. I can't recall any illegal ones being used in murders, but maybe some escaped my notice. Legal or illegal, they are demonstrably not a problem; in fact, the NFA of 1934 used them as a wedge to try to severely restrict handgun ownership, but that failed in the Congress.
