Somewhat related to the question regarding what can be used against you in a court of law, on a local bike forum that I access there is a discussion about how local police used a rider's cell phone history against him to gain a conviction. Now, he was completely stupid - outran local police and helicopter and dumped his bike in the Tampa International Airport parking garage. The police found the bike, but no rider. They came knocking at his door early in the morning with an arrest warrant. His defense was that his bike was stolen and he had no idea that it was gone. Then the State Attorney shared evidence with his defense attorney showing that his cell phone had provided gps information that proved that his cell phone, which was in his possession when he was taken into custody, took the same route as the 'stolen' bike at the same general time as it was being chased. They threw the book at him and he's screwed. The moral of that story is if you are planning to go out and ride stupid, remove the battery from your cell phone first.
