Bang ... bang ... bang ... bang ... bang ... bang ...

San Francisco District Attorney George Gascon announced this afternoon what always seemed likely: if police officers can claim that they think they are in danger, or perhaps someone else is in danger, they can shoot a man six times in the back. Officers Eric Reboli and Craig Tiffe face no penalty for killing Guatemalan immigrant Amilcar Perez Lopez on Folsom Street two years ago. A man is dead. This is the law.

This outcome doesn't speak well for the law. Or for justice.
