ICE buys tool to monitor millions of smartphones. Experts say it’s dangerous

In a redacted acquisition document obtained by the tech news site 404 Media, the immigration agency proposes entering into a contract to buy “all-in-one” tools from a company called PenLink that will allow agents to “compile, process, and validate billions of daily location signals from hundreds of millions of mobile devices.” The document also mentions payments for services involving “face detection,” “advanced face search,” and a “dark web data feed.”
