According to the National Law Enforcement Officers Memorial Fund, a total of 1,539 law enforcement officers died in the line of duty during the past 10 years, an average of one death every 57 hours, or 154 per year.
There were 120 law enforcement officers killed in 2012.
It's a profession where the line between life and death can come together in the blink of an eye.
Sergeant Travis Walker experienced that first hand last weekend while trying to arrest a Nashville man.
Walker has been an officer for 19 years
He's pulled his gun before, he's been in tough spots before, but this past weekend was different.
According to Walker, a 26-year-old man named John Sinks was riding a dirt bike down a road and wouldn't pull over.
"I turn the blue lights on just to say, ‘Hey, get off the road, you know better'. He looks at me, passes me, and laughs. We go about another mile and I'm thinking he's just a country boy being dumb," the officer explained.
"When he got off the bike, he had a look in his eyes, looking a little aggressive, and I said, ‘Now get on the ground'," Walker continued.
Walker said Sinks refused to get on the ground, began using vulgar language and started walking towards him.
Sinks was acting aggressive, agitated, and unpredictable.
Walker pulled his gun and takes a stand, while thoughts of life, death and family fill his thoughts.
"You gotta go home. You gotta go home to your family, your kids, and this guy wants to take it for some reason. There's a gun involved. I have it. It's on my side. And he doesn't care. If you shoot him, will you be prosecuted? You know you are going to be sued, that is how society is," Walker explained to Nashville's News 2 Investigates.
"If he beat me, would he have got my gun away from me? Would he have shot me?" he continued. "I'm going to survive. I have to survive. I have a family, kids, a wife, and friends. I'm not leaving this world."
Eventually, Sinks surrenders.
While cuffed, Sinks kept threatening the officer, saying things like, "I oughtta come back and beat ya right now."
He is charged with resisting arrest and evading.
Sinks has a criminal record, including a charge of disorderly conduct for becoming belligerent in Skyline Hospital when he didn't like the prescription medication he was given.
