The protesters, many of whom were affiliated with the Laborers International Union of North America and Alexandria-based Tenants and Workers United, were noisy but peaceful. Their hour-long protest was watched closely by a dozen Arlington County police officers.

The demonstrators were protesting two recent actions that they say amounts to a “war and persecution of Virginia’s immigrants.” Last week, Virginia Gov. Bob McDonnell barred the Department of Motor Vehicles from accepting “employment authorization documents,” commonly used by immigrants, as proof of legal residency. Then this week, the U.S. Immigrations and Customs Enforcement Agency revealed a change in policy that will put illegal immigrants charged with DUI on the fast track to deportation.
