Former Uvalde school police officer Adrian Gonzales was acquitted on charges of child endangerment, but the trial, and its focus on active shooter training, are still sending ripples through law enforcement agencies in Texas.

Prosecutors put an employee from the Southwest Texas Law Enforcement Academy on the stand and asked her to read several passages of an active shooter training that Gonzales taught a few months before the shooting.

After Gonzales was found not guilty, his attorneys say this may have been the first time a Texas officer’s active shooter training was used against him in the courtroom.

“Its purpose was never to have somebody be prosecuted, who went through a class, because they weren’t able to perfectly gather everything about a training or apply that training in a situation the training never contemplated,” said Jason Goss, one of Gonzales’ attorneys.

Goss said the case should serve as a wake-up call for police agencies.

“They need to be aware that their training is being used… to criminally prosecute police officers, and honestly, in this case, it wasn’t right to do that to Adrian,” Goss said.

We also spoke with Mark Eiglarsh, who represented former officer Scot Peterson, acquitted after charges tied to the Parkland school shooting. Eiglarsh warned that prosecutors often hone in on training.

“They’re always going to use the training and say you didn’t do this, you didn’t do this — but the facts are always unique,” Eiglarsh said. “You can only train so much. What happens is unforeseeable things at every scene, like where exactly is the guy, or radios start to fail, or fill in the blank. So training is only so good as the scenario in which you’re presented.”

Active-shooter training requirements in Texas have changed significantly since the Robb Elementary tragedy.

Most notably, Texas peace officers must now complete at least 16 hours of ALERRT training every two years, replacing older programs like the one Gonzales once taught.

Supervisors are required to take additional training to prepare them to lead during these incidents.

Many school districts now must have a designated school officer on campus.

Districts hold trainings once per year, or more often, to practice active shooter protocol.

Pam Revels of the National Association of School Resource Officers says the goal remains prevention and adaptability.

“If we can stop it before it happens, that’s what we want to do,” Revels said. “You get training, but that should not be it. Every time one of these events happens across the country, across the world, you should go back and reevaluate, are we ready and prepared for this?”

Former Uvalde CISD Chief Pete Arredondo is expected to face trial for his role in the Robb Elementary shooting, though a date hasn’t been determined yet. It’s unclear if training will be examined in that case, too.

Goss mentioned departments could potentially add disclaimers to training documents to make it clear they’re not intended for use in criminal proceedings, but it’s unclear whether that’s the current standard across the state.
