(VIDEO) Wickedness !!! Angola Police brutally and mercilessly beat helpless women

why do some African police behave like animals most of the time especially when they are in the force or have a upper hand? 

This is so degrading and a shame to Africa as a whole. The video you are about to watch shows how Angolan police maltreat and brutally torture women. It's alleged that this is how the police torture the Angolan population. Don't watch the video if you have got a fragile heart because it will break. One of the women in the video is even an handicap, but that didn't stop the police from beating her mercilessly with woods, canes, police sticks, kicks, blows, slap and even feeding them with fresh pepper.
