Tarpon Springs, Florida -- It's called "Cop Watching," where people tape police officers as they make stops and arrests. Tommy Frane says it's not that people who do the taping are against police officers, but they want to hold them accountable, like they do all public officials.

Investigators who set up a sting operation Monday had hoped to snare two corrupt Philadelphia police officers suspected of robbing drug dealers - just not the two who fell into the trap. These disclosures raise the possibility that as many as four 25th District officers have been robbing couriers, stealing cash and giving the drugs to another dealer to sell, sources said. "I don't know how deep this runs," Police Commissioner Charles H. Ramsey said in an interview Thursday. "We've got a lot of work to do."
