No, it is not, and many young men (not just musicians) have encountered such. I believe that most manage (by some combination of thinking with the big head, sheer dumb luck, and the Grace of God) to avoid doing anything criminal ... but it can be a close call, sometimes.
As you and I can probably attest as we are today, we see this type of thing and say, "How can anyone be so stupid?"
But upon reflection, I say, "How did I ever survive being 18?"
