Simple improvement: ban carriers from charging for this surveillance. Could even introduce it as a pro-cop anti-corporate measure, which should take care of the political fringes. That removes the incentive to make it easy.<p>Next, some manner of heightened threshold for more than N consecutive tracking requests or M requests in a twelve-month period. Maybe probable cause? This will be harder, politically, particularly in a law & order cycle. (Maybe it could be accomplished through rulemaking at the FCC.)
