Radar for things other than speed..

As a part time libertarian (Sorry Reason magazine, but we don't need open borders, you are way off on that) I generally respect a "man in his castle," if you will. To the point my duties require me to go on, I don't try to invade another man's privacy.

Now this is something interesting. This would more accurate be called a scanner as opposed to a radar.

Police Start Using New Radar Guns That Detect More Than Just Speed

Police officers use radar guns to detect the speed of drivers. These tools come in handy because they make it easier for officers to pull over people who are speeding. The radar guns clock the driver’s speed. However, that is not the only thing that these radar guns can detect. Many people believe that police officers are only using these guns to track speed, but an officer can also use the gun to see whether a person is texting and driving.

Texting and driving is a serious problem. Despite the fact that there have been a lot of studies done to confirm that texting and driving is dangerous, many people still choose to do it. Some states have even made it illegal for people to text and drive. A company in Virginia has developed the guns.

These radar guns work by detecting radiofrequencies. The frequencies come from the cell phone. Sending a text message will give off a different frequency. If the police officers detect a text message frequency, then they will know that the person is texting while driving. This new radar gun is not on the market yet. However, it will be in the hand of officers soon.

I doubt they will be in the hands of cops anytime "soon." I gather it's still in development phase and it will have to be certified by the federal and state authorities. But point made, it's in the pipeline.

It will be very interesting to see how the courts rule on this.
