Well for starters, not allowing open air drug dealing and arresting illegal drug dealers in the streets. Cooperating with ICE, and so on. Starting to take action against homeless that do refuse housing because they enjoy the homeless lifestyle, which in turn will make it less attractive for non-native homeless to come to San Francisco.
Cooperating with ICE to send these people back to America where they come from? My, my, San Francisco’s atavistic parochialism is really something but calling ones fellow Americans illegal immigrants. That’s good.
