Excellent query.
Thousands of San Francisco landlords, shopowners, citizens and tourists demanded action to clean city streets and empty them of drug addicts, homeless criminals, and filthy sh*t disturbers, but were told for years that it couldn't be done.
Before throwing a party for commerce leaders and overseas dictators, the cleanup gets done. Useless Democrat "leaders" in SF who care little about citizens; they don't run Bartertown.
