São Paulo is a place where creativity and originality are celebrated, and it can be experienced through music, design, fashion and gastronomy. Though the pace of the city is similar to other financial capitals, like New York or London, it has a particular dynamic that is unmistakably Brazilian and is a result of the diversity that makes up the city.
I am a Londoner, but I live and work in São Paulo in Brazil. This week I collected my Brazilian permanent ID card. It's taken months of bureaucracy and many visits to the policia federal in Lapa to get this far.
No modern police service can refuse to engage in dialogue with the citizens they are there to protect and Facebook is just a relatively recent way for the police to talk to the public. If they choose to start deleting intelligent questions that question their policies and behaviour then they may as well forget about counting on the public - the people who pay their salaries - for support.
