The FCC has ruled these devices to be ILLEGAL, and on appeal a federal court
upheld the Commission:

Er, not quite. They ruled that ONE specific jammer was illegal...whereupon the
manufacturer put the same works in a different case, changed the model number,
and began marketing it again. The device you heard the ad for it NOT illegal,
as far as the feds are concerned. A few states ban their use.

The funniest aspect to the whole thing is that they don't work. By the time
they have sent a jamming signal to the police radar unit, the radar has already
displayed the vehicle's speed. Using the device also assumes that the cop is
stupid. If the cop sees a car traveling considerably faster than the rest of
traffic, and that car displays a speed a great deal different from the rest, he
or she is going to know that something's not right.

Not illegal, or not enforced? (the Feds never chased down and
prosecuted the pirate FM that operated in my hometown for many years.
Surely that doesn't mean the operation was legal?)

Good point. Though to a large degree the damage is done if the user
*believes* he can speed without risk, even if he's wrong.
