Sometimes children have to be locked up because they put themselves in danger by running away and being prey to predators that use them sexually and for drug distribution. If you had a kid that runs away continually and sleeps in the streets and wants to be a 'gansta' and a 'hustler' just like in the videos, the only thing you can do as a parent is to have them locked up until they mature. At least, preserving their body for a little while longer while giving them a chance to mature and change.
