As officers arrested Dalton High School social studies teacher Jesse Randal Davidson, his students spoke their minds on social media.
Police say that just before noon, students tried to get into Davidson's classroom, but he wouldn't let them in.
The teacher, later identified as social studies teacher Jesse Randall Davidson, 53, was taken into custody without incident about 30 to 40 minutes later.
Davidson has been charged with "aggravated assault, carrying weapon on school grounds, terroristic threats, reckless conduct, possession of gun during commission of a crime, and disrupting public school", according to Dalton Police.
The school building was placed on lockdown and students were then evacuated to the Dalton Convention Center.
It's still unclear why Davidson was armed or why he fired his gun inside the school, this shooting is a reminder that arming teachers is not going to solve the problem of mass shootings.
He added that the teacher would face "appropriate charges because this is a very egregious act that took place at the school".
'I feel like there just shouldn't be guns at school at all, ' she said.
Under questioning by detectives, he refused to discuss what led to the shooting.
In another report previous year, police said officers found Davidson during a school day sitting on the curb of a street, conscious but unresponsive and being held up by two school staff members.
While no one was injured by the gunshot, one student was injured during the hectic evacuation of the high school.
"But this one was real", student Wesley Caceres said.
Frazier said there was no evidence Davidson was trying to fire at anyone.
Bartoo said he knocked on the door and put his key into the lock when Davidson "slammed the door closed and said, 'Don't come in here, '" Bartoo said. The students told the principal, who tried to enter.
He was finally found sitting on the curb along a street a few blocks from the campus, being propped up by two school staff members, police said. Classes will resume on Friday. But a spokesman says apparently the teacher DIDN'T intend to harm any students. He said he wanted to confess to having had a woman killed.
Dalton teacher accused of firing a handgun in his classroom had three rifles taken away after setting the family auto ablaze at his home two years ago, according to a sheriff's report obtained Friday by The Associated Press. A school resource officer was visiting the district's junior high school at the time of the incident and had to be called to the scene.
