[ Politics ] Open Question : Why does BLM base their origins on something that didn’t happen?

BLM started when it was reported that Michael Brown was shot even though he was just standing there with his hands up. Eventually the truth came out. The DOJ investigated and learned that Brown charged the officer before he was shot. That happened under Obama and even Obama admitted that the police were justified in their actions (shooting Brown). In essence, BLM is based on a lie and still chant “Hands up, don’t shoot” at “protests”. If they were honest, shouldn’t they abandon that phrase? “The movement became nationally recognized for street demonstrations following the 2014 deaths of two African Americans: Michael Brown …and Eric Garner” https://en.wikipedia.org/wiki/Black_Lives_Matter
