This brings back memories of New York in the 1980’s when the Guardian Angels got their start.
Now in Rio de Janiero armed vigilantes are pushing the drug dealers and other assorted low life from the slums of the city.
Sometimes law enforcement fails. The key part of it fell towards the end of the article, police can be bought in some areas of the world. And even where you think it can’t be, sure enough the cops can be bought.
So it takes others to rise up and do the job. The problem is they run afoul of all sorts of ordinances, statutes, etc. Even today the Guardian Angels take a little bit of flak.
