I agree that lives matter, and I am not attempting to justify bad shootings by cops. However we need to not be so quick to automatically think a cop is a racist, or a murderer, or evil person because they shot someone. Many of the police related shootings are the result of having to make a split second decision. An officer sees a gun, they cannot take time to decide if it is a toy gun, an unloaded gun. It is a gun, and therefore a threat. If they don't take immediate action, then their inaction could lead to the death of an innocent person, or the police officer themselves.Even if the person was a complete lowlife, we don't just shoot people. Lives matter.
I would love it if we lived in a world where things like this would never happen, but they do, and the best thing we can do is allow the investigation go forward and determine the facts of the case, instead of automatically deciding the cop is a racist killer.
