BLM started because there for a while about once a week we were being treated to stories of yet another unarmed black male being shot by police. The African-American community was rightly upset, and thus "Black Lives Matter" was born. Just like any political movement it may have been hijacked by other groups with other agendas, but I bet one thing they would like to accomplish is being able to drive home after work without wondering if they're going to be gunned down by an overzealous cop with an itchy trigger finger for Driving While Black.
