In Boston, Massachussetts police worked exhaustively with the faith community... And it helped that city go two years without a single juvenile homicide death.
Minneapolis, called "murderopolis" by the New York Times in 1995, cut its homicide rate nearly in half in one summer by teaming police up with probation officers who knew who the troublesome teens were and who was likely to retaliate after a violent crime.
Richmond, Virginia launched a "do it with a gun and you go to jail" program. It got guns off the street.
Chicago put desk cops on the street on weekends to beef up patrols. And - most importantly - they used cameras to watch and to deter.
Chuck Wexler with the Police Executive Research Forum says, "They would put cameras in areas that had been well-known drug locations where street drug traffic had occurred and those cameras very often had a significant impact on reducing street activity."
Wexler told Action News Five by phone that cameras are less expensive than manning a corner for 24 hours with an officer.
And he points to Washington, D.C., where he says the police brass meets every single day for two to three hours to discuss the previous 24 hours of crime.
Wexler continues, "Highly unusual. There's no other major police department I know in the country that has a daily systematic crime briefing with the top people."
