I will try and get my cop friend to let me know what service they use or exactly how it works. He told me how they were able to get the phone number of any phone that stopped moving or stopped transmitting in the vicinity of the parked cop car. They can get the owners information without a warrant. If a fatality or injury is involved they send a warrant request for the recent text messages and call logs, and the speed at which the phone was traveling during those calls/texts. It's all recorded by your carrier, not the phone. Blew my mind when he told me this!They need a reason to be investigating you in this manner...I don't believe they can call up Rogers.
