What you need to know about the FBI’s data collection system for tracking people’s movements

The FBI has a data collection program called Metros, which has been collecting personal information on Americans since 2001.

It also monitors millions of devices around the country, according to the bureau’s inspector general.

The FBI collects and stores data from about 1,000 devices, including those that track GPS devices and cellphones, according the inspector general’s report.

That includes information on where you are, where you’ve been, how often you go to work, when you travel and how often.

The agency can use that information to target people with “substantial criminal or terrorism-related activity,” the report said.
