Today the AP reported that the US Supreme Court will take up the case to decide whether the use of GPS devices violates the fourth amendment to the Constitution's ban on unreasonable searches. Apparently, the police secretly installed a GPS device in a man's car and he was subsequently convicted for operating a cocaine distribution ring. The conviction was overturned on appeal, and the US Justice Dept. has now appealed to the US Supreme Court. What do you think? If you are from a country outside of the US, do you know what's legal there?
