According to an internal DHS document obtained by 404 Media, Customs and Border Patrol has been tracking the people’s movements through online advertising data purchased with our tax money.

Through many popular apps including game apps like Candy Crush, weather apps, fitness apps and dating apps like Tinder and Grindr, back end advertiser bids have allowed DHS to purchase the location data of millions of phones without any warrants to do so. And finally, lawmakers are attempting to hold DHS accountable for its warrantless purchasing and surveillance of location data from brokers who have no qualms handing it over to the highest bidder.
