Cops are doing exactly what they want to do. In my opinion, that means killing non-white people. That is their job and it always has been their job. We live in a society that will do anything to prevent the success of a non-white person. I am not suprised. Angry, but not surprised.
They are not necessarily actively avoiding non-lethal means to confront criminals. While they are not necessarily discouraged at this time, 11 deaths in a country with such a large population does not indicate that the police are making a conscious effort to avoid less lethal means. However, they should be watched more carefully and thoroughly examined by an outside party when things like this happen.
Law enforcement are trained in a variety of areas, however, it would appear that officers are quickly resorting to weapons or violence in order to calm a situation. This is proving to be deadly and the result is that people are losing their lives. By training cops in another method of peace-keeping, we can ensure that they are doing their very best to turn a bad situation into a calm situation as effectively as possible.
I disagree that just because someone was killed by a cop, they employed the wrong type of action. There are so many criminals out there with guns and cops are under fire quite a bit. If someone is coming at a cop or at another person with a gun or deadly weapon then the cop should shoot.
