Attorney David Lane says the ruling Wednesday ended the lawsuit because it was designed to stop the alleged harassment.
U.S. District Judge Robert E. Blackburn ruled that protesters didn't present compelling evidence that police had stepped up enforcement as a way to retaliate and silence protesters.
Two people testified they were ticketed for honking a car horn and a hand-held air horn in a show of support for the protests.
Another person said he was ticketed for stopping briefly in a no-parking zone to donate warm clothing to protesters.
