The cop is right about there being another way for them to catch you. It's a computer based device that doesn't set off the detectors that they use to catch you from behind when you're moving. My friend is state trooper in CT and explained it to me once. It looks at your car moving in relation to something else that isn't, like the lines on the road to clock you.

The guy who said laser jammers are not illegal is also wrong. You're interfering with law enforcement. Good luck arguing that it's legal. edit - the jammer is legal. JammING is going to get you in trouble.

And don't get caught speeding in VA. Depending where you are, they will throw your ass in jail for 1-3 days regardless of the speed. There's a story on Jalopnik about one of their writers with a ZL1 getting locked up a few years ago.

For the app, I use the escort paid app with detector. It marks every cop that anyone else with an escort detector has marked either manually through the app or by the detector itself. Waze is good for a free app, but you're going to get a ton of outdated markings when the cop's long gone.
