On Saturday night in Austin, Texas, a Black Lives Matter protester named Garrett Foster was shot and killed after a chaotic altercation with a motorist who apparently tried to aggressively drive past marching protesters in an downtown intersection. Foster was openly carrying an AK-47 rifle during the protest, which is legal to do in Texas. Austin Police announced on Sunday night that the driver said that he fired on Foster after he pointed his rifle at his car, while some witnesses have said Foster did not. The law enforcement investigation is ongoing. Below is everything we know so far.
