It took about three seconds. After three seconds and 10 well-placed shots, then-CIA contractor Raymond Davis had killed two men he believed meant him harm and sparked a diplomatic disaster between the U.S. and Pakistan that lasted more than six weeks.

But three seconds earlier, Davis’ only concern in the world was the pistol in the hand of Pakistani man on the back of a motorcycle just ahead of him in traffic.

“I’m sitting there, I’m looking to my left and I start to look back to my right as I look around and I see a gun,” Davis told SOFREP in a recent interview. “I see, the guy begins to rack the gun and I’m like, ‘Oh damn,’ so I start going for mine. So [the man’s] gun goes from out of the holster to being racked, to starting to come up.”

The 2011 incident in Lahore, Pakistan is the centerpiece of Davis’ new memoir titled “The Contractor,” where he writes that time appeared to slow down for him as he drew to fire for the first time in combat, how he’d be trained to do a million times.

“As soon as I saw the gun’s muzzle moving in my direction, I unclicked my seatbelt and started to draw the gun I was carrying in a waistband holster beneath the front of my shirt… as soon as my gun cleared the steering wheel and was aimed at my intended target, I started pressing rounds out of the chamber, squeezing them off as I would with a fully automatic weapon.

“I had never killed anyone before,” Davis writes. “Thankfully, all ten rounds I fired found their intended targets.”

To this day the intention of the two men is unclear, and Davis notes in the book they may have been thieves out to rob him or potentially members of a terrorist organization with designs to kill any American military contractor. Either way, Davis was less than sympathetic.

“Any time lives are lost it’s tragic, but I wasn’t going to lose a bit of sleep over killing these two men. Once the man on the back of the motorcycle pulled his gun and pointed it at me, he’d made his choice, just as I made a choice to defend myself,” he writes.
