Florida Gov. Rick Scott on Thursday vowed to keep guns out of the hands of mentally ill people after a deranged high school gunman killed 17 people.

“If somebody is mentally ill they can’t have access to a gun,” said Scott at a press conference a day after a day after Nikolas Cruz allegedly mowed down students and staff at Parkland’s Marjory Douglas High School.

Cruz, who is charged with 17 counts of premeditated murder, purchased the AR-15 he used to carry out the carnage at the South Florida school legally.

Broward County Sheriff Scott Israel revealed at the press conference that there was an armed “school resource deputy” on the school’s campus while the gunman was active — but “he never encountered Cruz.”

Israel also said “there have been copycat threats made at other schools” as of Thursday.

“We will respond to every threat,” Israel said.

He took the opportunity to urge anyone who feels someone else’s actions raise a “red flag” to report it immediately.

“If you know anybody who says this raises a red flag, call us. If there’s something in your gut that tells you there’s something not right not with this person,” he said.

Broward County Public Schools Superintendent Robert Runcie said students in the area have been contacting to demand “a real conversation about gun control laws in our country.”
