The Ninth Circuit Court of Appeals just decided that it was legal for the police to put a GPS tracking device on your car, sitting in your driveway, on your property. Here's how to protect yourself.
Matt's post about the decision explains more about the ruling. To quickly summarise, the supreme court says that police can look through things that anyone in the public could come across, meaning, your driveway is freely accessible to the public, hence, the cops can shove a GPS locator onto your car. Then they can use it track you. Without a warrant.
How do you stop this without combing over the underside - or perhaps even inside - of your car and finding the GPS tracker? With technology.
Your first bet is probably to find out if someone is tracking you or not. You can turn here for mobile phone and bug device detectors. But these aren't 100 per cent, so if you're really paranoid and want to hide your location, you'll want to just go ahead and stop the trackers anyway.
The first type is a GPS jammer, which is technically illegal to buy and use in the US, so keep that in mind. These types of GPS jammers plug into the cigarette lighter in your car, and will "prohibit GPS signal" up to 10 meters. Ten metres isn't too far, but it isn't super close either, so cars next to you might get some GPS interference as you drive down the road.
If you're worried that someone is tracking your mobile phone, there's a signal blocking bag for about $US10 that you can shove your device into when not in use.
You also have the mobile phone-type trackers, which need to be stopped with a different device: a mobile phone jammer. There are various portable versions, as well as ones that go into your car. These types of jammers are as illegal as the GPS ones, so again, know what you're getting into.
Is it worth it to go to the potential legal troubles of owning and operating a GPS or mobile phone jammer if you're not doing anything wrong? That's up to you to decide. But if you are doing something that you want to make sure the government doesn't know about and they're already spying on you, it might already be too late to get one of these. [The Jammer Store]
