Stealing Secret Syrup

While you're sneaking around him, the guard sees you, and then runs at you and tackles you to the ground. You try to fight to get him off, and manage to throw him off you and draw your gun at him. He puts his hands up, and says "you got me, don't shoot!"

You handcuff the guard and leave him tied at his desk while you keep going into the building to find the formula, but what you don't know is, the guard had handcuff keys in his back pocket!

Before you could even go into the next room, the guard unlocks himself, draws his own gun and shoots you in the back.
