Outgoing San Francisco Mayor Gavin Newsom made a bold announcement this week when he tapped the City’s police chief, George Gascón, as the new District Attorney.

Here in Arizona, we recall Gascón as the former top cop in Mesa. There, he made headlines for butting heads with Sheriff Joe Arpaio.

As Newsom and his staff ruminated on a new police chief (just before the mayor was about to leave to begin his new job as California Lieutenant Governor), someone recalled that Gascón is also a lawyer (he graduated from Western State University College of Law in Fullerton, Calif., and was admitted in 1996).

San Francisco Public Defender Jeff Adachi

That new hire helps seal San Francisco’s ranking as top city for unique criminal law leaders. Jeff Adachi, the city’s Public Defender, also has a reputation beyond the state’s borders. We wrote about Adachi here, when he visited Arizona in regard to a movie–and a protest in regard to the signing of SB1070, our immigration law.

As always, the city is worth watching.
