no, that's a mandatory thing someone has to do when going to prison. They do that to make sure they aren't sneaking in weapons, or drugs
Why would a 13 yr old put a weapon or drugs up his butt?
bro there are really fucked up things in the world so this is 100% possible
A kid doing that is 100% possible? The cops should have explained in more detail about what they were getting ready to do but they didn't.
this is just a manga. in real life they explain everything.
Did the kid get sexual assaulted?!
