The group filed a federal lawsuit Wednesday in Fort Worth. Its members hand out Open Carry literature and copies of the U.S. Constitution while armed with long-barreled guns and black-powder pistols.
The Arlington city council amended a 1994 law on the handing out of leaflets, making it less restrictive. Two Open Carry members had been ticketed for giving out literature during a demonstration.
Assistant City Attorney Robert Fugate said the ordinance is a safety measure.
"The ordinance doesn't have anything to do with guns," he told the Fort Worth Star-Telegram. "There are many other places in the city where they can go about their business, distributing copies of the Constitution or distributing bananas. The content of their speech is irrelevant to the ordinance."
But Warren Norred said that even the amended ordinance violates the First Amendment: "They passed a law to stop people from handing out the United States Constitution. Really?"
Fugate said the city plans to enforce the amended ordinance. The amendment took effect Thursday.
