The reason the Floyd killing has been such a powerful force is that there is a live video of a man being strangled, begging for his life, for minutes.

It is much easier to discredit a split second decision, mistaken identity, justify feeling threatened in so many other cases, but there it is, a man immobilized on the street with a knee on his neck, people standing around objecting to what’s happening, time, so much time to consider actions when there was no reasonable threat.
