The "young criminal" sense is no doubt the inspiration in punk rock first attested 1971 (in a Dave Marsh article in "Creem," referring to Rudi "Question Mark" Martinez); popularized 1976.
If you looked different, people tried to intimidate you all the time. It was the same kind of crap you had to put up with as a hippie, when people started growing long hair. Only now it was the guys with the long hair yelling at you. You think they would have learned something. I had this extreme parrot red hair and I got hassled so much I carried a sign that said "FUCK YOU ASSHOLE." I got so tired of yelling it, I would just hold up the sign.
