United Students Against Sweatshops sues D.C. police

WASHINGTON (AP) - The D.C. police department has responded to a lawsuit accusing an undercover officer of infiltrating a protest group.

The department acknowledges having used at least one undercover officer to monitor the group but say they followed all appropriate laws.

The lawsuit from United Students Against Sweatshops accused an undercover officer of attending its protests earlier this year under the guise of being a fellow demonstrator.

Police are permitted under certain circumstances to use undercover officers to monitor First Amendment activities, including if they believe the organization is planning to commit a crime.

In a sworn statement, Thomas Wilkins, executive director of the intelligence fusion division, says he approved using undercover personnel to monitor the group as part of an investigation into the assault of a uniformed officer at a protest.
