(CNN)Once again, we're talking about arming teachers as a solution to gun violence.
After a student gunned down 10 people Friday at a high school in suburban Houston, some Texas elected officials are resurrecting the idea, which has been floated by President Trump and debated across the country since the Parkland, Florida, school shooting in February.
But in state after state, the proposal so far has largely failed to gain traction.
In the three months since Parkland, 14 states have proposed 25 bills or resolutions related to arming school personnel, according to data from the National Conference of State Legislatures. Only one of these measures has been voted into law -- in Florida, where lawmakers in March passed a bill which arms some teachers if both the local school district and local sheriff's department agree.
A spokeswoman for the nation's largest teachers union says it's no surprise these legislative efforts are failing.
"The overwhelming majority of teachers oppose being armed," said Mary Kusler, senior director for the National Education Association's Center for Advocacy. "Teachers want to be in their classrooms to teach their children ... it is incredibly hard to do that when you're packing heat."
