After the Florida senate narrowly passed landmark gun and school safety legislation, Martha MacCallum spoke to the father of one of the Marjory Stoneman Douglas High School shooting victims.

The legislation, sponsored by Republican Sen. Bill Galvano of Bradenton, raises the minimum gun purchasing age to 21, sends millions of dollars to school safety and mental health initiatives, and gives schools the opportunity to arm staff.

Martha MacCallum said the measure stopped short of explicitly arming "teachers."

Andrew Pollack lost his 18-year-old daughter Meadow on February 14, and told MacCallum he hopes no one "has to feel what I have to feel."

"When someone murders your kid, shoots her nine times, it kind of empowers you. ... It drives me every day," he said.

Pollack applauded the State Senate's passage of the bill, and said he would be in Tallahassee personally to oversee the House's consideration of the legislation.

He said he would be on the floor engaging with each lawmaker to make sure they voted for it, and if they planned not to, he indicated he would ask them why not.

"I'm going to focus on what I could do," he said. "I want to know why [lawmakers who vote 'no'] don't want our kids safe."

He added that gun control is not the answer to school shootings, pointing to the hundreds of such incidents in American history.

"Every focus right after the shooting is gun control... and it doesn't work," he said. "Let's change it this time."

"We owe it to our kids," Pollack said.

He recalled how on a recent trip to the Department of Education in Washington, he rode an elevator that was staffed with an armed guard.

He said there's no reason why such a situation cannot translate to school property, calling metal detectors and other security measures "the new normal."
