Isolated violence is not uncommon in small towns in South America, no matter what country you are, but it´s usually related to crime and drugs, and similar stuff. But the new elements are really something to worry about.
The story starts when Hugo decided to arm civilians (illegally) with AKs to defend the supposed revolution going on. With a pocket full of money to buy Caribbean countries loyalty, and whoever crossed in his path, no one cared about it and what effect this would have in our society. He was going to do whatever he wanted, and so he did. Yes, Hugo, arming people in da hoods was a GREAT idea. Thanks for nothing, moron. Afterwards, the few people really decent who had the terrible idea to receive a weapon would be screwed: many of them were victims of criminals looking to take the guns from them. These AKs and handguns would be under control of the "colectivos", a word used to mask illegal activities like express kidnapping, blackmailing, retail drug business and small scale money laundry, under organizations that would do "community or social/cultural work" for the poor barrios.
Far from the truth.
