The principal tweeted that clear backpacks are out and the school will start a pilot metal detector program.

The school is also altering the fire alarm tone.

Back on February 14th when accused shooter Nikolas Cruz Entered the Freshman building and shot and killed 17 students and staff, the smoke from the gunfire set of the fire alarm.

That sound is a painful reminder of the chaos and tragedy that ensued.

“I like the metal detectors,” said Stoneman Douglas student Gabriella Figueroa.

Figueroa was in an adjacent building and heard the gunfire. She hid in a closet and lost friends in the massacre.

“No one is gonna bring anything cause you have metal detectors. I feel a lot safer too.”

She is glad that they will no longer have to carry ‘clear’ backpacks because of privacy issues.

All schools in Broward, not just Stoneman Douglas will see enhanced safety measures in the fall.

All students and staff will need to wear identification badges.

The district is working on limiting access points to all schools.

We asked parent Cesar Figueroa what else he’d like to see. H said, “Someone video checking and interviewing kids is a good measure.”

“The school, FBI and BSO, everyone failed. We have to learn from it,” he added.
