The story last year of the US resident who discovered a Government owned GPS tracker attached to his vehicle was widely reported and sparked a huge debate on the legality of evidence gathered using them.  The row looks set to re-ginite with the discovery of two new models of GPS tracker, this time attached to the vehicle of a as yet nameless 25 year old Californian resident.

This initial device pictured above (Photos courtesy of wired.com) was removed from underneath his Volvo SUV, examined and photographed by Wired.com.  It was then replaced by persons unknown with a different device which is pictured below, this time the device was a Sendum PT200 GPS Tracker with a modified battery pack. There was also a sighting of a suspicious person investigating the underneath of his girlfriends car whilst she was parked at work.

The Justice Department reports that GPS trackers are regularly employed in the fight against crime, something that the vast majority of the general public are probably unaware of.  The strange thing is that there is no warrant requirement to use these devices, the government can just attach one to your vehicle and begin tracking your movements without probable cause and without it having to be authorised by a judge. 

Everybody, check underneath your cars, you never know what you might find!  You can read the original wired report at http://www.wired.com/threatlevel/2011/11/gps-tracker-times-two
