Trump's DHS appointees have dismantled civil rights protections, allowing agents to remain anonymous and wear masks, while also threatening groups that oppose them and overwhelming legal challenges to their tactics.
A recent example of this is when Immigration and Customs Enforcement officers stormed through Santa Ana, California, in June, prompting panicked calls to the city's emergency response system.
Recordings of those calls, obtained by ProPublica, captured the terror residents felt as they watched masked men ambush people and force them into unmarked cars.
ProPublica is a nonprofit newsroom that investigates abuses of power, providing in-depth reporting on such incidents.
