Faced with the grim reality Philadelphia is now averaging about one to two murders per day, Mayor Nutter has announced a number of crime-fighting initiatives, including cash — $20,000 for tips that lead to the arrest and conviction of a murder suspect, and $500 for information that leads to the arrest and conviction of thugs who carry or sell illegal guns. Temple criminologist Jerry Ratcliffe, who has helped the Police Department develop crime-fighting strategies, said "the more-specific, focused strategies have the best chance of succeeding. . . . It's a good chance to try something new."
