The San Francisco Police Department has recently launched a new initiative to fight drug dealing near schools. As outlined in this article in the San Francisco Chronicle last Thursday, the police department is targeting drug dealers within 1,000 feet of San Francisco schools who are dealing heroin, crack, or methamphetamine during school hours . . .
