black lives matter started because of shooting of unarmed black men on camera by the police
if you weren't so hateful you wouldn't be so concerned with BLM
police getting killed has nothing to do with BLM
No, BLM started after Trayvon Martin was killed by George Zimmerman. Martin wasn't killed on camera and Zimmerman wasn't the police.
