Because they have a license to kill. There can be no doubt that it was a death squad that assassinated Amadou Diallo. Three of the four police officers have been involved in shooting incidents within the past two years. It is despicable that these killers are not in jail without bail. It has a social function.
Cops protect the interests of the rich and keep the poor in line-by any means necessary.
So, they build prisons, hire cops, arm cops with machine guns, tanks and helicopters. Both parties are corrupt to the core and dedicated to serving their rich masters. Every day cops harass Black men, women, and children throughout New York City- for no reason other than the color of their skin. They have developed a low- intensity class warfare of harassment, disrespect, and violence, especially toward young Black men. The criminal injustice system has decimated an entire generation of youth who, denied a decent education and decent jobs, are left adrift on the street with no future.
