The father of one Parkland school’s shooting victims has done an investigation into the events that led up to the massacre. He wanted to find out why it happened and is now able to warn others on how to recognize the warning signs and do something about them.

On Feb. 14. 2018, Nikolas Cruz opened fire with a semi-automatic at Marjory Stoneman Douglas High School, killing 17 people and injuring 17 others. Andrew Pollack’s daughter Meadow was one of the victims who died. “I wanted to look into it, I wanted to honor my daughter to see what happened, and how it could happen that I put my daughter in a school, in a nice neighborhood, and then I’m never going to see her again,” Pollack told host Tomi Lahren on Fox Nation “No Interruption.”

“I wanted to know the facts. I didn’t just listen to mainstream media. I didn’t jump on that bandwagon. I found out that there was a multitude of failures and policies that lead up to my daughter getting murdered, that the mainstream media didn’t want to cover,” he said.

Pollack has written a book on his investigation titled, “Why Meadow Died: The People and Policies That Created The Parkland Shooter and Endanger America’s Students. He wants to give parents and grandparents a guide of how to be able to spot warning signs of potential shooters. “Uncovering all of this,” said Pollack, “it did a lot for me so other parents now can learn from it and that’s what brought me to this book. And the book started as just an investigation, but there were so many jaw-dropping failures that I had to educate other parents.”

Policies put in place by the Democrats have created the situations that allow these mass shootings to take place, he said. The new gun control laws are ineffective, as other measures are not carried out said Pollack. “To me, gun control would’ve been if they arrested him for punching his mother’s teeth out and he got a background,” explained Pollack. “

“Democrats put these policies in place that don’t believe in holding kids accountable or arresting them while they’re juveniles … so if they don’t arrest them and they don’t get a background, then they’re able to purchase weapons legally and a background check is useless,” he added. Banning guns will not solve the problem. “They’re not addressing mental health … or arresting these people when they make threats … those are the real issues,” he explained.

After watching a video of 2020 Democratic candidates promoting gun control, Pollack commented it had made him feel “ill.” “My daughter paid the ultimate sacrifice because of those Democratic policies, and I’ve been hurt by the Democrats more than anybody in this country—and I hold them responsible,” Pollack said.

He met with the president five times and is impressed with his initiative of the Federal Commission on School Safety to investigate what changes need to happen to keep students safe at school. “Every time that there’s a mass shooting,” he explained, “I think about these victims. Like the ones in Walmart or the ones in Virginia at the building where these animals are coming through, and they’re shooting—and I picture my daughter being a victim.”
