An increasing number of law enforcement agencies, including the US Secret Service, are simply buying their way into data that would ordinarily require a warrant, a new report has found, and at least one US senator wants to put a stop to it.

The Secret Service paid about $2 million in 2017-2018 to a firm called Babel Street to use its service Locate X, according to a document (PDF) Vice Motherboard obtained. The contract outlines what kind of content, training, and customer support Babel Street is required to provide to the Secret Service.

"The database reviewed by The Times—a sample of information gathered in 2017 and held by one company—reveals people's travels in startling detail, accurate to within a few yards and in some cases updated more than 14,000 times a day," the paper wrote at the time.

Apps are not the only ones collecting and selling that information. All four national mobile carriers—Verizon, AT&T, and the now-combinedRead More – Source
