When it is a given that a guy fired a single shot at a stranger that had him pinned down and had been beating the sh** out of him for almost a minute, it’s hard to charge him with anything other than maybe chipping the concrete with his head. And since the other guy controlled his head at the time it’s hard to make even that stick.
The “riots” have been underwhelming. They needed something on the Rodney King scale to make much out of this.
