In Rio de Janeiro there is a huge gap in wealth and social stratification. Beautiful high-rise buildings overlook spiraling slums creeping up hills. A city where the poor deal with the corruption of drug lords in your neighborhoods as their governing body, and the rich deal with the same corruption of drug lords on a less blatant platform, but that deals with a greater sum of money.
Over the past few years the police of Rio de Janeiro have been slowly taking over the "drug lord's" turf in the slum (favelas) and permanently reclaiming the land and power as Brazil's. The series of operations have not been peaceful or been done without some type of retaliation from the escaping drug traffickers.

Let's all hope that there are no more innocent people killed or wounded by this all out war between authority and anarchy. Which leads me to the question: why did the government let it get to this point? Also, knowing that drugs kill people, innocent people and ruin the lives of loved ones, why do people (rich & poor) continue to use and create a demand for these illicit crimes. Stepping onto my soapbox--people, love your neighbor and do good to each other. Treat those how you would want to be treated.
I'll leave you with a quote by Ganhdi, "You have to be the change that you want to see in the world." Please don't create a market for blood shed.
