Months after missing Star Wars Lego sets brought a California YouTuber to Utah, people who helped Ben Schneider during his visit are suing American Fork, alleging police violated their constitutional rights.

The lawsuit, filed Wednesday in the U.S. District Court in Utah, names the city and 13 police officers it says were involved in a series of encounters spanning four days in March. Among them are officers involved in a traffic stop, nearly two hours of roadside drug and alcohol testing and arrests at an Airbnb that ended without criminal charges.

The four plaintiffs are Sheldon David Norcross, an Illinois resident, and three Utahns: Tyler Matthew Shaw, Sierra Nicole Lauts and Steven Allen.

American Fork Police Chief Cameron Paul defended his officers’ actions in a 26-minute YouTube video posted in May. But at later recorded meetings with an American Fork resident who had questioned officers’ conduct, the lawsuit says, Paul acknowledged that “we didn’t do this perfectly” and that several matters “weren’t handled well, or were handled outside of policy.”

Those admissions, the lawsuit alleges, along with body camera and dash camera footage and police reports, show that officers violated the plaintiffs’ constitutional protections against unreasonable searches and seizures and restrictions on government interference with free speech.

The complaint alleges American Fork’s “indifference” to people’s rights enabled the officer’s actions. That’s because, the filing states, the city staffed its patrols with inexperienced officers, failed to properly train them on traffic stops, phone seizures and search warrants, and did not enforce safeguards required by its own policies.

Four days of police run-ins

The police run-ins began on March 8, when an officer pulled over Shaw for allegedly failing to stop at a stop sign, according to the complaint.

However, after reviewing footage, Paul said in one of the recorded meetings that he did not “believe there was a stop sign violation” and that the officer “clearly misremembered” the law, the complaint states. The department has since reviewed the statute with the officer, it says.

Paul maintained that the officer had reasonable suspicion to make the stop for another reason, the complaint states, but said the officer “should have based his stop on that reasonable suspicion to begin with and not try to have drummed up some kind of other offense.”

The next day, police stopped the car Shaw and Schneider were in, questioned them and put them through drug and alcohol testing for nearly two hours, despite officers having no reason to believe either was intoxicated, the lawsuit alleges. A police dog also sniffed Shaw’s vehicle for drugs.

That’s because, according to the complaint, Paul said sometimes officers may “help somebody understand the gravity of the situation and make it appear very serious to them or as serious as it is,” before letting them go.

Then on March 10, Lauts, who was acting as a process server for Schneider, tried to deliver court papers to Johnson. Officers instead questioned her and issued her a trespass notice, the complaint says. Lauts was qualified to serve legal papers in Utah and had waited in her car for Johnson to come outside, without stepping on his property, it states.

The following day, Norcross and others were filming a donation video when officers arrested him and seized his phone, the complaint states. Norcross spent more than four hours in custody, much of that time under interrogation, before officers released him without charges, according to the complaint. Police later returned his phone.

Later that day, officers also entered a nearby Airbnb where Schneider had been staying. They were carrying guns and went in without knocking or announcing their presence, the lawsuit alleges.

Officers arrested Shaw, Lauts, Allen, Schneider and a 16-year-old at the Airbnb. Only Schneider was charged.

Paul later acknowledged problems with the search warrant, according to the complaint, stating that it was “one of the biggest places where we screwed up.” It was not reviewed by a supervisor as required, he said, and “we should have never even put Legos in this affidavit.”

“This didn’t really have anything to do with Legos,” he said, according to the complaint. “We weren’t going in to look for Legos. We didn’t even search the residence for Legos.”

The lawsuit seeks compensatory and punitive damages, to be determined at trial, as well as attorney fees and other costs.

It started with missing Legos

It all began with a dispute involving valuable Star Wars Lego sets consigned to an Oregon franchise of Bricks & Minifigs, a Utah-based Lego reseller.

It has escalated through viral videos posted by Schneider, who has accused the American Fork Police Department of misconduct and bias. The backlash has included threats and harassment directed at the department and regional dispatchers.

Schneider alleges the company and its former Oregon franchise owners, Josh Johnson and Brandon Best, stole the sets and that police protected them because they appeared to be members of The Church of Jesus Christ of Latter-day Saints.

The Lego dispute has spawned dueling lawsuits and hours of YouTube videos that have drawn millions of views.

Provo-based BAM Franchising Inc., which franchises the Lego resale chain Bricks & Minifigs, announced in August it had agreed to settle its dispute with the Lego owner, Bryan Mansell.
