Amid heightened concerns about firearms in the wake of last month’s Parkland, Florida, high school shooting massacre, Santa Clara County officials are taking another look at banning gun shows from the county fairgrounds.

The Santa Clara County Fairgrounds currently hosts two gun shows a year. But county Supervisor Ken Yeager said gun shows conflict with the county’s mission of “promoting the health and well-being of our residents” and have drawn complaints from residents.

“More and more often, I am getting approached by people who tell me how disturbed they are when they see billboards or signs advertising gun shows at the fairgrounds,” Yeager said. “That is not a use they want to see at one of our most prominent public spaces.”

The board of supervisors is expected to consider Yeager’s proposal March 6.

The fairgrounds just hosted a Code of the West San Jose Gun Show on Feb. 10 and 11 put on by the Fullerton-based California Rifle and Pistol Association. Rick Travis, the group’s executive director, said in response to the proposal that “owning a gun is legal in the United States even when politicians do silly campaigns like this. We suggest he reads the Constitution.”

Supervisor Dave Cortese, who’s hosting a summit on reducing gun violence in April, said Yeager’s idea is worth exploring if it can be done without preventing other activities the county supports — like gun buy-backs aimed at reducing the number of privately owned firearms in the community. Other supervisors had no immediate response.

Steve Stagnaro, marketing director for the fairgrounds’ management, said the organization will follow the supervisors’ direction and that losing a couple gun shows a year wouldn’t be a financial pinch.

“We manage at their behest — if they set a policy of no gun shows, we absolutely will abide by that,” Stagnaro said, adding: “It would be minimal impact fiscally on the fairgrounds.”

Yeager said the most recent show generated about $6,000 in revenue for the county.

It’s not the first time Santa Clara and other Bay Area counties have tried to ban fairgrounds gun shows. In the late 1990s, the Santa Clara County board tried to shut them down with a fairgrounds lease amendment.

But in 1997, the Ninth U.S. Circuit Court of Appeals overruled that effort, citing First Amendment protections for commercial speech. The decision, however, left open the possibility of restricting gun sales more broadly on all county property.

In 2012, after a long-running court battle, the Ninth Circuit upheld an Alameda County gun show restriction with provisions the court called “reasonable” such as requiring guns to be tethered to display tables by a sturdy cable.

The proposed Santa Clara County gun show ban comes amid ongoing efforts to rethink the fairgrounds, which occupy more than 100 acres in central San Jose that critics say are underused.

Gun shows aren’t the only activity to fall out of favor at the fairgrounds. Fairgrounds management recently decided against keeping the 10-acre motocross track, one of only two of its kind in the Bay Area. Suggestions for a fairgrounds overhaul have included using some of the land for affordable housing or sports fields.

Yeager said his proposed ordinance would not infringe on legitimate gun owners’ rights to lawfully possess or use firearms on private property. But he said the county has had four shooting deaths so far this year, though none associated with gun shows.

“Last month’s horrific shooting at Marjory Stoneman Douglas High School in Parkland, Florida, is another tragic reminder of how fast and easy it is to commit mass murder with a gun,” Yeager, who has hosted county gun buy-backs, said. “We can’t eliminate the threat of mass shootings, but we have a responsibility to do everything we can to reduce the risk of them.”
