This article from the Christian Science Monitor gives more detail to the Altanta ICE crackdown that lead to ICE agents harassing U.S. citizens because they looked undocumented. The court case, which alleges that ICE officials "used 'Gestapo-like tactics' as part of a deliberate campaign of fear ordered by the Department of Homeland Security."
The sad reality about this raid, and other localized tactics that are designed to terrorize and aliente the undocumented, is that they also distupt the day-to-day lives of the citizens and legal permanent residents or anyone who might look like a Latino. The more serious issue is that ICE officers are accused of violating the civil rights of the undocumented and citizens alike. And while undocumented workers are violating federal law, current federal workplace rules give anybody who is employed and drawing a paycheck certain protections, no matter their residential status.
