I work in a police dept. doing IT in the Madison Area. Every time police go to a location, the GPS coordinates are logged into a server. Every single squad car has a GPS device and is tracked at all times. In the case of the officers it's important because if an officer can't talk on their radio, dispatch still knows where they are.

Personally, I think the police can get a lot more done if they don't have to physically follow someone. Ever heard of a stakeout? GPS tracking on a car is much less of an invasion of privacy than a detective watching your every move. I don't see what the problem is. It saves the taxpayers a lot of money when they're not paying a cop to sit and watch someone all day. If you read the article you'd also note that GPS tracking was used to determine that a man was stalking a woman who had come to them with a complaint and he was arrested and charged based on the evidence.

Also, most phones have GPS and if you don't have it turned off, you can be tracked in much more detail than with a unit on a car. So this is making a stink but everyone's already forgotten about Bush's warrentless wire-tapping. I'd rather be tagged than tapped.
