Police can't be everywhere, so 11-year-old Landon Wilburn is on patrol in the Stone Lakes subdivision in Louisville. Landon told The Courier-Journal he used to shout at speeders to slow down — then had a better idea.

Dressed in a reflective vest, wearing a bicycle helmet and armed with a Hot Wheels brand radar gun, he points and records the speed of passing traffic.

The boy also carries a flashlight with a built-in siren.

Subdivision resident George Ayers said he has seen drivers lock up their brakes when they saw Landon clocking them.

Officials say the city will install speed bumps in the neighborhood if 70 percent of residents agree and are willing to put up half the money.
