Law enforcements have a new tool in tracking suspected criminals, but complaints are suggesting that it goes beyond the realm of what should be legal without a court order.
With the costs now only a few hundred dollars each, it's now cheap enough for law enforcement to hide GPS transmitters on suspected criminal's vehicles and track their movements via satellite. The law enforcement argument is that when you're driving, you are out in public and have no expectation of privacy.
The other side of the argument is that you're also being tracked when your vehicle isn't out in public, but so far, courts are siding with law enforcement.
Wonder how long before you'll be able to buy devices to help you locate those GPS devices. I always loved in movies when they would find the device and attach it to someone else's car and suddenly this old couple would find 200 marines with machine guns pointed at them.
