Immigrant justice advocates are denouncing reports the Biden administration plans to expand its use of home confinement and to launch a pilot curfew program to monitor undocumented immigrants awaiting court hearings. The move is said to be part of an effort to decrease the use of private immigration jails. But rights advocates say the U.S. government is not only incarcerating more immigrants but also growing more reliant on ankle bracelet monitors and other surveillance devices as so-called alternatives to detention. Axios reports as of last week there were nearly 180,000 immigrants subjected to these practices, though the actual number may be much higher as current figures only account for the head of a household registered in such programs.
