How about:

-when The Police target known bad guys, tail, surveil, nail and jail them, sending them to prison when the points/probation add up.

-when The Police perform probationary enforcement, sending a multi-convicted felon back to prison for violating probation (curfew/alcohol/hanging w/dirtbags) thus preventing more crimes.

-when the Police do sex offender verification, and send them to prison for not keeping a current address, or not listing an alternative address, thus preventing them from committing further crimes.

-when the Police aggressively target areas of high crime, which is noticed by the criminals doing the crimes, who then move elsewhere.

-when the Police enforce zoning for bars/hotels, thus preventing "attractive nuisances" reducing crime.

-when The Police provide fraud prevention education for businesses

Those are just some of the things that go on daily in a Police Dept that the average Joe is unaware of.
