New Hampshire's highest court says the conduct of a band of self-styled Robin Hoods who feed parking meters while following meter readers is protected under the First Amendment. But it says the city of Keene has a right to pursue an injunction against them in the interest of public safety.

City officials said they have no problem with the group paying the fees but want to protect parking enforcement officers from harassment and argued for a buffer zone. Some employees said they've been bumped and sworn at.

The state Supreme Court ruled Tuesday the "challenged conduct" is intended to draw attention to parking enforcement operations. There's no allegation that it involves violent conduct.

The court said the trial judge was wrong to deny an injunction without considering all the circumstances of the case.
