The murder of George Floyd in Minneapolis was a watershed moment for many Americans.
Seeing Floyd's life choked away while he begged for his life, hearing onlookers begging Derek Chauvin to remove his knee from Floyd's neck and seeing the officer refuse to do so, reveling in the fact he had the power to do what he wanted with no obvious fear of reprisal is an image that will be a part of United States history as long as there is a United States.
It's caused a reckoning. It's convinced many of us who were slow to grasp that a mindset which leads to a moment like that truly exists.
