This is absolutely wrong and is a very good example of why the current hysteria over illegal immigration is a bad thing. We are a nation of immigrants. We shouldn't be so paranoid about immigrants that we're willing to treat citizens like crooks.
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 and jailers for days, with no communication with federal immigration agents to clarify the situation.
