President Donald Trump suggested on Wednesday that arming teachers and school staff members could provide security against events like the shooting at Marjory Stoneman Douglas High School last week, in which 17 students and school workers were killed.

The idea was widely panned — especially by veterans with experience using high-powered weapons and firing under duress.

"Shooting under stress is extremely difficult. Even for the most well-trained shooters," Jay Kirell, an Afghanistan veteran who has written about difficulties veterans face in civilian life, tweeted. "A teacher is not going to be able to do this. Cops & soldiers literally get paid to do this & most of them can't shoot accurately under stress."

"Not because they suck, but because it's nearly impossible to hit a target in one shot when pumped full of adrenaline," Kirell added. "And if you're in a school with a shooter and dozens of children, if you're not shooting accurately you're just creating crossfire."

Data compiled by the New York City Police Department underscores the difficulty of firing accurately in challenging situations.

In 2005, NYPD officers intentionally fired their guns at someone 472 times, hitting their mark 82 times. In 2006, New York police fired under the same circumstances 364 times, hitting their target 103 times. That same year, Los Angeles police fired 67 times, recording 27 hits.

Other veterans responded directly to Trump, dismissing the idea of arming teachers as inappropriate and dangerous.
