Police officers held the second in a series of active shooter response training classes Sunday in Grove City.
The class is designed to teach citizens what to do in case of horrific scenarios like what happened in Chardon or Newtown, Connecticut.
The drill, held at 3226 Kinsgton Avenue, had the feel of reality for Grove City residents.
An instructor, acting like an armed intruder, fired off blanks as a group was huddled in a classroom. The ear piercing shot and frightening scenario left some still shaking after it was over.
"You could hear it coming, you knew it was coming , but when it was there it really made you feel vulnerable," said Janet Smith, who came to the training with her husband.
"You knew he was probably going to break through the door like she said, it was real scary just there's nothing you can do to stop it," said Ed Smith.
Officer with the Grove City Division of Police say this active shooter response training is designed to prove that common theory is wrong.
A series of exercises and a movie clip showing what happens to innocent lives when people do nothing, left students shocked and saddened.
"It's just a reality, there are violent people in the world and if we can provide information to as many people as possible hopefully that'll swell," said Sgt. Rick Hardy with the Grove City Division of Police.
Students are told the worst thing they can do is take no action and that immediate response is key.
They're told to use anything at their disposal is they're trapped in a room to keep that intruder out.
"Hiding is the last thing you want to do, if you can get out, get out if you have to fight it's a fight for your life you have to be committed, dedicated to that action," said Hardy.
Police say the primary goal is that these citizens never have to use what they've learned, but instructors say if they've learned it, then they have a much better chance of survival.
