What is your viewpoint on the police racism issue?

I am doing a project for school where I have to write about a controversial issue. I hold this issue dearly because I always have believed that it is wrong to own or treat someone different because of their skin color. Now I do not support the BLM movement. I think they are taking things way too far. But on the other hand, I seen the George Floyd and Philando Castile videos and those officers were way out of line and deserve to be thrown in general population. I know that police must make split second decisions but, you cannot tell me that officer that killed Mr. Castile was scared for his life. You do not empty a 16-round clip into someone. Especially when he never made a move like he was drawing a gun. If I am correct, he even told the officer that he had a permit to carry and was just reaching for his license. I do not blame the officer for being nervous, but I do blame him for his actions. Let me know what you think.
