taking pictures should only be restricted to own group of friends - taking pictures of the crowds or other people can immediately result in a confrontation.

A key to both staying safe at a baile funk and ensuring an easy exit from the favelas after the fun is over is to avoid getting inebriated in any capacity.

While consuming illegal substances and drugs  is always a bad idea, doing so and engaging with drug dealers in a favela is not only illegal, but it is highly dangerous -  there is no way to determine the true composition of any substance, serious side effects can occur, and immediate medical assistance would likely be unavailable.

Similarly, excessive consumption of alcohol increases vulnerability to a wide variety of negative outcomes, by affecting good behavior, good judgement, and common sense.
