"I'm just sad the governor vetoed it," said Rob Schaaf, a Republican senator from St. Joseph.
Senate Bill 656 would have allowed designated school teachers or administrators to carry concealed weapons after undergoing training.
"Arming teachers will not make our schools safer," Gov. Nixon said. "I have supported and will continue to support the use of duly authorized law enforcement officers employed as school resource officers, but I cannot condone putting firearms in the hands of educators who should be focused on teaching our kids."
Rick Dulac has grandchildren in the St. Joseph school district.
"I fear for them somewhat, I know St. Joe is kinda a moderate crime rate town," he said.
"I was happy with the way it was worded," said Senator Schaaf. "I thought there was adequate protection. Look at what happened around the country when gunmen go into schools. If they happened to be armed right there, then they could have put a stop to it immediately."
Parents like Dulac, say they just want their kids to be safe.
"I feel like there may be other ways instead of arming teachers to protect our schools such as security guards, more security of that measure," he said. "I feel like it could be a better means of protecting our children."
And for now districts around the state will look for other methods to protect their children.
