A state commission investigating the Parkland high school shooting in Florida that left 17 people dead has recommended arming teachers — an idea that President Trump has espoused since last year’s massacre.

The 15-member Marjory Stoneman Douglas High School Public Safety Commission on Wednesday issued its report aimed at preventing similar attacks and improving the response should they occur.

“All stakeholders … should embrace the opportunity to change and make Florida schools the safest in the nation,” the report says, according to USA Today. “There must be a sense of urgency — and there is not, across-the-board — in enhancing school safety.”

The report, which slammed the response of school workers and the Broward County Sheriff’s Office to the Valentine’s Day massacre, puts the responsibility for reform on school districts, law enforcement agencies, Gov.-elect Ron DeSantis and state lawmakers.

Some of the recommendations laid out in the report would require action by the governor and state Legislature, including allowing some teachers to carry guns and increasing spending on school security.

Florida law already allows districts to train and arm administrators and other staffers — but teachers must have a military or police background to carry a firearm, the news outlet reported. The report recommends that teachers who volunteer and undergo extensive background checks and training be allowed to pack heat.

The committee argued that the educators are often the first line of defense in school shootings and encouraged laws to arm more of them.

In the wake of the attack, Trump embraced a National Rifle Association position to arm highly trained teachers.

“If you had a teacher who was adept with the firearm, they could end the attack very quickly,” he said at the time, stating that schools could arm up to 20 percent of their teachers to stop “maniacs” who may try to attack them.

“They’d go for special training and they would be there and you would no longer have a gun-free zone,” Trump said. “Gun-free zone to a maniac — because they’re all cowards — a gun-free zone is ‘Let’s go in and let’s attack because bullets aren’t coming back at us.’ ”

But the state teachers union does not support arming teachers, and some law enforcement officials have voiced opposition to the proposal.

Former New York City Police Commissioner Bill Bratton called arming teachers “the height of lunacy.”

The report also calls for laws allowing school districts to raise taxes for security improvements and to require — rather than simply permit — mental health providers to notify authorities if a patient threatens anyone with harm.

Pinellas County Sheriff Bob Gualtieri, the commission chairman, said many recommendations could have been implemented long ago had school safety been given priority, the Sun-Sentinel of Fort Lauderdale reported.

“There needs to be a sense of urgency,” he said. “And people need to understand that there’s an expectation and a rightful expectation on the part of parents: When you send your kids to school in the morning, there’s an expectation they’re going to come home alive in the afternoon and there are very basic things.”

The report says the Florida school district and sheriff’s office were unprepared for the attack by Nikolas Cruz, 19, who previously had been expelled from Parkland.

Sheriff’s Deputy Scot Peterson, the school’s resource officer, was among the officers who were criticized for failing to immediately confront the shooter.

Sheriff Scott Israel told the commission that he had earlier eliminated the policy that required cops to confront active shooters because he didn’t want them to venture into “suicide missions.”

Armed with a semi-automatic assault rifle, Cruz entered the school building and fired more than 100 shots before the gun apparently jammed.

A grand jury indicted him on 17 counts of first-degree murder that could result in the death penalty.

The commission’s report now goes to DeSantis, Senate President Bill Galvano and House Speaker José Oliva.
