According to a recent report, the crackdown on immigrants also snares plenty of Americans.
Immigration Crackdown Also Snares Americans - NYTimes.com:
A growing number of United States citizens have been detained under Obama administration programs intended to detect illegal immigrants who are arrested by local police officers.
In a spate of recent cases across the country, American citizens have been confined in local jails after federal immigration agents, acting on flawed information from Department of Homeland Security databases, instructed the police to hold them for investigation and possible deportation.
Americans said their vehement protests that they were citizens went unheard by local police officers and jailers for days, with no communication with federal immigration agents to clarify the situation. Any case where an American is held, even briefly, for immigration investigation is a potential wrongful arrest because immigration agents lack legal authority to detain citizens.
