For almost two years, members of the Marjory Stoneman Douglas High School Public Safety Commission have been studying the causes of the shooting and the systemic failures surrounding it.
Their goal is to prevent another Parkland, and make schools safer.
Senator Lauren Book represents Broward County in Tallahassee, and she is the only lawmaker on the commission.
"I feel a great sense of responsibility," she said, "and it's one of the most difficult things I've had to ever parse apart."
"When I look at the two fathers who sit on the commission, when we go through some of this stuff, I'm embarrassed at the way this system, the entirety of the system, we have allowed to continue on."
The Senator pushes back against the notion that the Parkland shooter was someone who simply slipped through the cracks.
Instead, she says, he was a known threat and someone was receiving services.
One of the problems, Senator Book told CBS12 News, is that the school system, law enforcement, and service providers weren't communicating and sharing critical information.
"Everybody messed up. everybody," Book said. "All of us. We all messed up. Every single kid in that building knew who that shooter would be."
The MSD Commission has already published two reports which can be found at this link.
Enhancing school safety, improving inter-agency communication, and funding mental health services are among the recommendations the MSD commission has released publicly.
Privately, Book said they are learning troubling information about the events leading up to the shooting that the public cannot know yet.
"We're still in a criminal proceeding, so a lot of the things that the members of the commission and the legal community and law enforcement knows, the general populous doesn't necessarily," she said. "There are a lot of things right now that privacy covers, that the commission has been able to see, that I can't talk about publicly because of the defendant's rights."
