Can you elaborate more on this please?
Sure
I moved to Brazil in the 90's. This is from Sao Paulo's point of view in my neighborhood Luz The amount of street children was insane. Some of them were in groups of 20 kids. Most of them were around just asking for food, or money. Most brazilians being very charitable, helped.
They didn't even had money to buy crack, so they used glue from shoes or nail polishers.
After some time things started escalating. Drug dealers would use the kids to sell drugs (the brazilian law has a Scandinavian esque type of law about minors not being held accountable for their actions). Some predators used street girls as their targets. Crack became easier to get, and with it handguns.
The people working around the area started to get afraid. Some of them were the same people who helped the kids with free food and money times ago. The kids grew and you could no longer see if they were minors or youg adults anymore.
Violence escalated after some years. Kids started robbing, murdering, raping.Police would try to get the kids, but by law they had to release them afterwards. It was on that period that one good friend of mine was murdered. A 14 yrs old kid robbed the store my friend worked in. The kid, having a power trip, decided to surrender my friend and play a game of russian rollette with my friend's head. He lost.
The cops started getting frustrated. Neighbors wanted justice. The government ignored the issue.
After some years things went totally out of control. People were willing to pay the police to exterminate those criminal kids who weren't considered responsible for their actions. They would beat the crap out of the kids, sometimes without any proof, take them to some places, and the kids would dissappear. Everybody knew what happened but was afraid to ask the cops. Between criminals who would target them or criminals who would target other criminals, they preferred the last.
These kids grew, many of them survived. Some of them went to a place we call Cracolandia (crackland) where they live as real life zombies. Others became powerful, extremely violent, and leaders. That's how the drug cartel in Sao Paulo became more powerful than Rio's.
