I'm a non-professional photographer looking to visit Rio and possibly Sao Paulo, I'm interested in shooting the life in the favellas but understand that it is a rather risky proposition in terms of chances of getting robbed or worse.
How should I go about arranging a "fixer" who will accompany me, communicate with the locals, help me navigate situations etc. while avoiding the more shady hustlers and "poverty porn" tour operators. ?
Is hiring an off-duty plain clothes police officer a viable option ?
