It seems as though we hear more about mass shootings and other tragedies in schools and other public places.
For most school districts, having an emergency plan is not an option.
Tuesday, Brownwood High School teamed up with law enforcement and other agencies for a mock emergency.
The drill simulated an actual lock down. Police responded as if there were a real shooter in the building.
Police entered the school rehearsing what they would do if a shooting had just taken place.
Once police secured the fake shooter, students were given instructions to evacuate the building.
Principal Bill Faircloth said this was the first mock emergency evacuation the school has practiced.
"The kids were absolutely fantastic leaving the building, never had to get on one. Out of a thousand kids, not one had to be gotten onto," said Faircloth.
Faith Bailey, a Junior at Brownwood High School, said the practice was good for the students.
"I think it's good that we were prepared, so now if something does happen we can know what to do, and we won't freak out and make stupid decisions," said Bailey.
Not only is it important for students to be prepared, School Resource Officer Fred Bastardo said the drill is vital for law enforcement officers.
"They also get a good lay out of the campus, know where the exits are, and basically know the general lay out; it helps a lot," said Bastardo.
According to Bastardo, there has never been an entire building evacuation at Brownwood High School.
The Brownwood Police Department, Fire Department, and Guardian EMS all responded to the campus.
