Late on a Friday, at the slowest possible time in the news cycle, when politicians make moves that they hope will get very little media attention, Mayor Gavin Newsom vetoed a plan to require police foot patrols in high-crime areas.  That marks a dramatic shift in his position.  Just a few days ago, he was prepared to sign the bill.
The veto sets up a fascinating showdown: Are there eight votes on the board to override the mayor? The measure passed 7-3 on its first round, with only Supervisors Aaron Peskin, Michela Alioto-Pier and Sean Elsbernd in opposition and Jake McGoldrick absent. Willl eight votes hold?
