Scot Peterson faces questions from Parkland dad’s lawyer.

For the second straight day, Parkland dad Andrew Pollack sat across the table Tuesday from one of the men he believes is responsible for failing to stop Nikolas Cruz from killing 17 people at Marjory Stoneman Douglas High School last year.

This time it was former school resource officer Scot Peterson, the Broward sheriff’s deputy who stayed outside the building while

Cruz went on a rampage inside. Peterson was denounced as a coward and resigned in disgrace after the shooting.

On Tuesday he sat for hours behind closed doors answering questions about his conduct last Feb. 14.

“He’s starting to get dementia, because he couldn’t recall a lot of things that happened that day,” Pollack said afterward. “He was reckless that day. If he would have went in, he would have saved my daughter on that third floor. … He’s haunted by it. I don’t have a problem with him being haunted by it. I’ll never see my daughter again.”

Peterson did not answer questions outside the courtroom after his seven hours of testimony. According to Pollack, Peterson claimed he called a “code red” emergency that should have put the school on lockdown. “It’s the first time we’ve heard him say that,” Pollack said. “We all know it’s impossible because no one was in lockdown.”

Peterson had an idea what to expect from Pollack’s attorneys — he was in the same Broward courtroom on Monday watching lawyers question former school watchman Andrew Medina, a co-defendant in the negligence suit Pollack filed last year. Others named in the suit include Cruz, who is awaiting trial for murder; James and Kimberly Snead, who took Cruz into their home in the two months leading up to the shooting; and Henderson Behavioral Health Inc., which provided mental health services to Cruz.

Attorneys in lawsuits are entitled to question the defendants ahead of time, but most of those depositions take place in private offices. Both Medina and Peterson have accused Pollack, whose daughter Meadow was among the victims, of trying to intimidate them online or in person.

Broward Circuit Judge Patti Englander Henning denied their requests to keep Pollack away from their depositions but ordered they be held at the courthouse to guarantee everyone’s safety.

The depositions are closed to the public — only the parties and their attorneys are allowed inside.

Peterson did not invoke his Fifth Amendment right against self-incrimination, as his lawyer did when Peterson was called to testify last year before the Marjory Stoneman Douglas Public Safety Commission.

Attorneys expect to continue questioning both Medina and Peterson at a later date.
