Nobody ever leaves CECOT alive so what are these gangs supposedly gaining by agreeing to this?
Loyalty from the gang members still inside.
Amazingly, gang leaders are very often able to operate even while in prison. And of course, there's possible hits inside of the prison system that need to be "taken care of" by members inside.
Prisons are just an extension, basically, for gang life.
I take one issue who you're replying to: Violent crime will go up, but first, there will be massive dollars on Bukake's head.
Well, because it would lead them to believe gang members are also being killed.
