Imagine the following situation:

Batman is on a rooftop, having just disposed of a sniper. Standing over the assassin's unconscious body, he hears a scream. Looking around with his binoculars, he spots a mugging taking place a few blocks away. Things are quickly escalating out of control. The victim is in imminent and quite possibly mortal danger.

They're way out of batarang range, and by the time Batman swung/jumped/ran to the scene, it would almost certainly be too late. On the other hand, the sniper rifle, intact at Batman's feet, has the range, speed, and accuracy to make the difference.

Batman swore he'd never use a gun, but it could be the only way to save the victim's life. But it's not a weapon he's used to. He has the hand-eye coordination, but not the experience. Closest thing he's used is the grapple gun. And the simple fact that he hates the weapon so much could potentially affect his ability to make an accurate shot.

What happens?
