I built a radar jammer, when in college, back in the 90’s. The issue is you end up setting off other people’s radar detectors, which just slows down traffic.

Most police traffic is on a trunked radio system shared with other users, and is typically encrypted. It’s easy find the transmission with a scanner, but trying to localize a transmission using only a power measurement is difficult due to multipath and fading.
