Possible Charges Dropped in Attack on Former SF Fire Commissioner.

The San Francisco public defender's office is seeking to drop charges against Garrett Doty, who was accused of assaulting former San Francisco Fire Commissioner Don Carmignani with a metal pipe. Doty's attorney claims he acted in self-defense after Carmignani allegedly pepper-sprayed him. The public defender's office alleges that Carmignani instigated the altercation and may have used bear or pepper spray against unhoused people in the past. The DA's office may drop charges against Doty if Carmignani is unable to testify in court.
