I don't think its a race thing, just terrible judgement by the cops
You do realize that the situation in New York City is the same as it is in Ferguson. Each have a DA that is a democrat. Each have a mayor that is a democrat. Each have a governor that is a democrat.
You must also be aware that the media is running with this with some incorrect info. This so called "choke hold" is not the one they have outlawed. The media has repeated said that the purpose of the choke hold is to cut off the breathing of the subject. If you will look into it the hold that has been outlawed in many cities is actually carotid artery hold. This actually cuts off the blood supply to the brain and the subject goes limp and passes out. I learned this technique in the Marines and used it many times over the years in law enforcement.
