As a very recent teacher who taught in an economically disadvantaged as well as typically middle class high schools, I have to respectfully disagree. The vast majority of students do a great job behaving. Even the kids involved in gangs in the two districts where I taught I found to be respectful. Percentage-wise in my recent district, very few teenagers get in trouble and even fewer involve the law.
I just thought that @jsroberts was making a joke that the school photos were like having mug shots every year for 13 years.
