TACOMA, Wash. -

A federal judge has dismissed a civil rights lawsuit filed against a man who infiltrated anti-war protesters in Olympia and gave information to security officers at Joint Base Lewis-McChord and police.

In his ruling Wednesday, Judge Ronald B. Leighton in Tacoma said John Towery had legitimate safety concerns in 2007 when he attended meetings of the Olympia Port Militarization Resistance. He was an employee of the force protection division for the Army base.

The Olympian reports the judge found that Towery did not chill political speech nor invade the privacy of protesters or influence police.

Officers arrested more than 60 people in November 2007 when they tried to block equipment shipments to the Iraq War.

A lawyer for the protest group, Larry Hildes, says he'll appeal.
