Stop and frisk emphasis patrols. I was city manager 10 years ago and we had 9 murders. I called the chief into my office and gave him his marching orders. He arranged on any given night over the next 6 weeks to have 20+ LEOs on duty. We had several other local agencies participate including sheriff’s deputies from 3 counties, police officers from cities 45 miles away, and state patrol. The final tally was no more murders and 77 felony warrant arrests.
I should mention that we were a city of 16,500 with a local Police force of 25.
