Radar guns are terribly inaccurate. In about 1 in 100 readings they are wildly off. Even when calibrated. I know this because my dad - who has an IEEE medal for his work on the laser, has testified as an expert witness on lasers and drives like an old Chinese woman - was clicked doing 90 in a 55 by a laser gun. He did the research and found the test results showing that in 1 in 100 readings you should expect an outlier such as reading 90 when the car was going 55. Guess what, it doesn't matter. No judge in the world cares. They aren't going to allow people to question the accuracy of these devices because it would destroy their revenue stream. Anyway, that's my rant on radar guns.
