Only 15 days after the terrible shooting at a school in Parkland, Florida, many believed that the fiery debate between the student community and the conservative right would quickly change things.

But at a school in Dalton, Georgia, alarms have soared again.

During Wednesday’s morning hours the hours, a social sciences teacher barricaded himself in a classroom without allowing any student in, and when the Director tried to intervene, the teacher fired a shot in the air, as TIME reported.

The professor, identified as Jesse Randal Davidson, would have pointed away from any person, and the police have not yet determined the reasons for his behavior that led to the immediate evacuation of the institution.

According to the police officers, a threatening note had been found days before in the school halls, but they discard any connection with Wednesday events.

Simultaneously, the Committee of Appropriations of the House of Representatives of Florida, of Republican majority, has voted in favor of creating "a state program to invest 67 million dollars in order to arm the teachers in the classrooms", following the recommendations of President Trump and the National Rifle Association after the events in Parkland on February 14, as reported by The Hill.

The program would allegedly cover the costs of background checks, drug and psychological tests, and a 132-hour training, despite the disagreement shown by Parkland's surviving teachers who noted the difficulty security officers would face in approaching another shooting if there were more armed people inside the schools.

But the serious incident this Wednesday in Dalton suggests that the problem remains in armed violence and that perhaps the most consistent idea is not precisely to increase the number of firearms in classrooms.
