8 Ways Police Can Spy on You Without a Warrant

1. Phone Records: Who You Called, When You Call

How they get it

Listening to your phone calls without a judge's warrant is illegal if you're a U.S. citizen. But police don't need a warrant — which requires showing "probable cause" of a crime — to get just the numbers you called and when you called them, as well as incoming calls, from phone carriers. Instead, police can get courts to sign off on a subpoena, which only requires that the data they're after is relevant to an investigation — a lesser standard of evidence.

2. Location Data: Your phone is a tracker

How they get it

Many cell phone carriers provide authorities with a phone's location and may charge a fee for doing so. Cell towers track where your phone is at any moment; so can the GPS features in some smartphones. The major cell carriers, including Verizon and AT&T, responded to at least 1.3 million law enforcement requests for cell phone locations, text messages and other data in 2011. Internet service providers can also provide location data that tracks users via their computer's IP address — a unique number assigned to each computer.

3. IP Addresses: What computers you use


How they get it

Google, Yahoo, Microsoft and other webmail providers accumulate massive amounts of data about our digital wanderings. A warrant is needed for access to some emails (see below), but not for the IP addresses of the computers used to log into your mail account or surf the Web. According to the American Civil Liberties Union, those records are kept for at least a year.
