The guy taking the video was a black worker who was concerned for the robber.
Does that surprise you?
The robber was armed with a knife, which he brandished, at the beginning of the video.
If the black person who took the video was a store worker, that worker should have been fired by the end of the day.
The store owners should have beaten the robber much more severely than they did. They should have also disarmed him and held him for the police to arrest.
But this is California, where the government is pretty clearly on the side of the criminals, particularly if they are blacks. It is not a situation that can continue. And it won't. This is just the start of the unravelling.
