BOPE and Policia Civil use to get bodybag fees, but they drove the murder rate up to 50k in one year, because your mom would have been an easy payday for them vs battles with AdosA and CV.
Believe it or not Rio is pretty passive. It's some zones which are buck wild like south west where they are feeding each other to reptiles. As noted, as a tourist, you don't have shit to worry about.
in south america you keep the poor in check with FREE housing, TV (sopa operas) and FREE food programs to keep their stomachs full.
Drugs are just from inequality equal to Africa. Balance the field similar to north america and 90% of the shit will go away.
Now...be warned a lot of ASSES are going to get jacked for the World Cup and Olympics but you can thank the Govt for that if you are one of the lucky few to get stabbed on Copa beach.
