How do you feel about juvenile detention centers?

American juvenile detention centers, anyway, because I don’t know if other countries even have anything similar. For those who might not be familiar with them, they’re basically mini-prisons for people under 18. Jumpsuits, jail cells, locked up behind massive barbed wire fences, etc.

So do you support them, oppose them, or fall somewhere in the middle? And why?

I have my own thoughts, but I’m interested in what the collective thinks.
