We can jokingly say things like “buy a cellphone jammer to silence those annoying people on the bus” but that would be irresponsible. Quite irresponsible, it turns out, as criminals are now using such devices to impede law enforcement efforts.

It happened last month in Canada. Two Mounties had pulled over a car, and as they approached to car their radios went out. It turns out that the two guys inside the pulled over car had turned out one of those $200 eBay cellphone jammers, putting the officers at unnecessary risk.

This is a good time to remind y’all that using cellphone jammers is illegal in the U.S and most other places. In fact, a first time offender faces up to a $1,000 fine for using a jammer in the U.S.

Seems to me that an iPod is a much cheaper way to avoid hearing a fellow commuter’s conversation. And anyone who uses a cellphone at a restaurant should be promptly shown the door.
