Colombian Army

I read about a week ago about a story that the Army in Colombia has been killing many of it's civilians. The Army has become corrupt, the soldiers have been killing innocent civilians and planting weapons on them to make them appear as gang members. They would do this to rank up in the army, and to also receive more pay and more days off. With all the gang activity in south america, and now reports of corruption in Colombia's Army seems absolutely terrible. I don't know what they could do now, it seems as though countries like this are soon gonna have no where else to turn to, to better the lives of the citizens of these countries.
