And , no , I won't fill you in on them. They are home playing on the net. The lines used to clock speeders aren't up to the specs that the state requires them to be. Have the police show documented proof that the lines are certified and were measured with a certified measuring device. One note, in Pennsylvannia, there are very few troopers who use radar guns.
Radar is too inexact for a police officer to use, therefore laser is a gun of choice.
Not only are these new guns undetectable unless they are aimed directly at your car, but they are nearly indisputable in court, since the beam is less than 1 inch in diameter. Troopers in Pennsylvannia, as well as several sections in our State of West Virginia, work in pairs. One car will do the clocking, while the other is already facing in the direction of traffic for a quick takedown. In exchange, the other cruiser clocks the cars coming in the opposite direction. I will admit these traps are VERY difficult to locate, even though they are almost always in plain view.
