Radar Detector mount...

[L.E. Sniper]

It doesn't matter, a rader or laser units beam
is not that narrow, most are mounted on the dash of the patrol unit anyway. It is true that the beam will bounce off the the front plate. There are radar and laser jamers on the market that work quiet well. One that I ran across a few years ago was made by Rocky Mountain Rader
In some states these are illegal, But so is speeding. The D.A. hear said not to worry about stopping a vehicle that is using one unless it is obvious that he is speeding (80 mph in a school zone)then we will also bust him for tampering with evidence. There is also a front license plate cover that defeats laser, these are also illegal, but all a officer in colorado can do about them is to confiscate the cover.
