I know foot patrol works. At least I think I know. I've done it.
But there's so little research out there. There's no reason we should all still be quoting a study from 30 years ago (which did show that foot patrol reduced public fear).
Foot patrol has worked in New York (it would work better without quotas). And now there's some research by Jerry Ratcliffe coming out of Philadelphia. As reported in the Philadelphia Inquirer:
Temple's study, which covered three months, showed a 22 percent drop in crime in areas covered by the foot patrols. Arrests were up 13 percent.
As in other major cities, crime has been on a decline in Philadelphia. Violent crime - down in all but three districts - dropped 7 percent citywide in 2009 compared with 2007, with homicide down 23 percent and aggravated assault down 4 percent.
