You have some valid points, but it doesn't make family members hurt less, because you can only name 4 people, when their brother, father etc is gunned down by a cop. I am not saying that every cop is wrong, there are instances where the shooting is justified, but there are also instances when the cop is wrong. We say Black lives matter not because we think that white lives don't matter. That has been taught to us for centuries. That movement is trying to remind people that we matter; as well.
