For police officers, the decision to use deadly force must be made instantly and officers say that decision must become second nature.
The Dougherty County Sheriff's Office uses a program they call "Run And Gun Training." It's a realistic scenario of movements and tactics that puts officers in a high stress situation.
"I'll holler at them, this and that and the other to induce stress to keep that heart rate up, to keep them where there not thinking as much. I want their mind running 1000 miles an hour. In a bad situation like that, that's what's gonna happen," said Training Sergeant Allen Brock.
The targets are changed after every shooter which makes it harder to decide whose friend and whose foe.
"Its repetition going through these motions over and over again, building that repetition does make it second nature and it give the deputy the advantage," said John Ostrander of the Dougherty County Sheriff's Office.
Training authorities say they keep the groups small in order to capitalize on one on one instruction. But they also keep it very real because when their life or the decision to take a life is on the line, they have to be confident with the choice they make.
