In a word, YES.
I'll relate a personal story here -- when I was a kid, I had an acquaintance who was approached by a guy with a criminal record as a child molester. This kid was 14, but he looked no older than 11 or so. The guy approached him in some kind of threatening manner, and this kid took one swing at him and dropped him right there on the sidewalk like a wet noodle.
The kid quietly disappeared, and the police were called to the scene. The guy actually claimed that he had been assaulted, but the cops knew all about his history. You could almost see them stifling their laughter as they "searched" for this kid. We, of course, had not seen anything -- in fact, we played right along with it.
"You mean that guy was assaulted by a little kid?"
