Horrible as this is, local vigilantes have been killing street kids in the favelas at least since 2005, which is when I first read about it.
These kids are absolutely feral and ferocious. It’s common for a gang of 10-year-olds to cut your throat and leave you to bleed out while they steal everything you have.
It was so bad, that you couldn’t even go out after sunset if you looked like you might have anything of value on you. They would kill you even for earrings.
Post #12 is NOT hyperbole.
It may be an understatement.
Helicopter transport is very popular in the cities of Brazil, to avoid the horrific carjackings.
