"Troops to be sent to Brazil's Rio to provide security for municipal elections" - Xinhua News

Rio's Governor, Cabral Filhos, known for his policies of heavy confrontation with traficantes, defended the decision saying it was to allow for free campaigning in all parts of the city and to prevent residents of the favelas from being forced to cast their vote for a candidate backed by a drug faction.
Well, ok. Fair enough. But then they're leaving, right?
"Cabral said the number of troops to be sent and the date would be set by the Superior Electoral Tribunal and state officials. He added that he intends to keep the troops there after the elections to help combat crime (emphasis is mine)." [1]Oh boy. Why do I have a bad feeling about this? Besides sounding a lot like martial law is about to be selectively put into affect, maybe it's because the last time the military was used to provide protection in a favela, things didn't work out so good. (we won't even talk about what happened in 2006)
