A private company is profiting from the use of GPS ankle monitors to track immigrants. B.I. Incorporated, part of the GEO Group, won a contract valued at $1.02 billion to provide these monitors and other services. So far, $228.5 million has been obligated to the company under this contract.

The GEO Group is already involved in immigration enforcement as a private operator of detention centers. The use of ankle monitors has become a significant source of revenue for the company.

Further details about the contract and the company's involvement in immigration enforcement are available from the source.
