BLM is 'supposedly' concerned about police brutality an its effect on the Black community.
The cases you cited are not related to police brutality an falls outside the scoop of BLM purpose.

It is obvious that these shootings are premeditated and carried out by villians or madmen, hence falls into the realm of terror shootings. So, why aren't the FBI all over these shootings like the shooting at the PP clinic?
