FBI Still Struggling With Supreme Court's GPS Ruling

Earlier this year, the Supreme Court said police had overstepped their legal authority by planting a GPS tracker on the car of a suspected drug dealer without getting a search warrant.

But after the ruling, FBI officials tell NPR, agents still had to turn off 250 devices that they couldn't turn back on.

"We have a number of people in the United States whom we could not indict, there is not probable cause to indict them or to arrest them who present a threat of terrorism. ... [They] may be up on the Internet, may have purchased a gun, but have taken no particular steps to take a terrorist act."
