Rep. Jason Chaffetz and Sen. Ron Wyden introduce legislation that would limit the ability of law-enforcement agencies to track a person's location through their mobile phone or a special tracking device. Says Chaffetz:
"I think it's great that GPS and tracking technology exists. What isn't great is the idea that this technology can be used to track somebody without their knowledge. It is the job of Congress to protect and defend the United States Constitution and the personal liberties provided to American citizens under the Fourth Amendment. Quite frankly, the government and law enforcement should not be able to track somebody indefinitely without their knowledge or consent, or without obtaining a warrant from a judge."
