It’s not “Black lives matter.” it’s “Black Lives Matter”. Capitalized.
After every police shooting of a black person, before any details arrive, before they can know what really happened, they start raiding, destroying stores inside their own communities and property of white people, this makes the media cover them instead of the case which is most likely confirmed justified at this point. This of course makes everybody think that there are so many shootings of innocent black people and the we need “Black Lives Matter”, and so the cycle continues.
No one disputed that black live matter, but those who think “Black Lives Matter” will often dispute that blue or white lives matter, so I will proudly say “all lives matter”.
