A former student of Columbine High School who was present at the 1999 massacre is now the house minority leader in Colorado and has introduced legislation to help prevent future school shootings like the most recent in Parkland, Florida.

State lawmaker Patrick Neville (R) wants K-12 teachers to be armed and he has pushed for this for the last four years. The Washington Times reports:

Under state law, concealed-carry permit holders may bring firearms onto school property, but must keep them locked inside their vehicles.

Mr. Neville, who has introduced the bill annually since he was elected in 2014, said the current law “creates a so-called gun free zone in every K-12 public school.”

A statement released by Neville read, “This act would allow every law-abiding citizens who holds a concealed carry permit, issued from their chief law-enforcement officer, the right to carry concealed in order to defend themselves and most importantly our children from the worst-case scenarios.”

“As a former Columbine student who was a sophomore during the shootings on April 20, 1999, I will do everything in my power to prevent Colorado families from enduring the hardships my classmates and I faced that day,” Neville continued. “Time and time again we point to the one common theme with mass shootings, they occur in gun-free zones.”

Unfortunately, Neville faces an uphill battle with Democrats in control of state politics. It’s expected that they will, once again, vote down the measure on Tuesday, leaving Coloradan children at risk for yet another year.
