TowDawg,
You are more than welcome to have your opinion about what traffic laws are for and not for. Rock on and not my concern. But as far as setting up large areas where police identify themselves to control speed and use only always-on in their cars, happens each and everyday.
As for ACTIVE jammers (let's call them scramblers because most people call them that), yes they are illegal all over. But, you are mistaken about passive shifters/"jammers" being legal everywhere, they are not. You are confusing federal laws and state laws. Check your local laws (has nothing to do if radar detectors are legal there or not either). The passive "shifters" that are available to the public will not do anything to a police radar/laser unless you are very very close in product testing, so I don't care about those. I am simply warning people to avoid anything that will activly try and scramble a signal because it will get them in far much more trouble then it's worth, that's why I said avoid "illegal shifters/jammers". The problem is that companies use too many terms like "scrambles, jammers, shifters" in an attempt to sell their products and people buy without knowing what they have.
Also, YES there are several active jammers (the illegal ones) that work very well. You are confusing passive shifters not being big enough to fit/hide in a car and active jammers (which work and can/fit in a car without issue).
