# Why did Bourne fire a shot in the air?

Bourne and Marie seeks refuge in Marie's ex-boyfriend Eamon's house.

The Professor arrives there in the morning.

Bourne grabs Eamon's shotgun and starts looking for The Professor in the field near the house. At first Bourne doesn't know where "The Professor" is. He fires a shot in the air. Birds fly. Professor leaves his current position. Bourne sees The Professor and shoots him.

What was the trick behind shooting in the air? And why did The Professor move?

-

It's a classical "I pretend to have to fired a shot, so you think I have revealed myself involuntarily, so you make your move, and then I get you because I'm ready" move.

The basic idea is a confusion. Bourne fires a shot, which would normally reveal his position. But, the birds are scattered along a wide area, so they create a mass distraction. The Professor now has some hint (from the direction of the shot's sound) where Bourne is, and tries to use it to his advantage, by moving in that direction.

This would work for "The Professor" just fine, had Bourne been distracted, i.e. if he fired a shot accidentally, or as a defense against some animal. Since the shot was staged, Bourne was ready and spotted him.

Had "The Professor" not moved, the birds would be useless to Bourne, but he instinctively moved and it cost him.

You said was I was just typing ... doesn't matter, as you said it much better than I was going to. – Pᴀᴜʟsᴛᴇʀ2 Oct 9 '13 at 10:40
@Paulster2 I'm sorry about that. One of the things I like on this site is that this happens here far less often than on Math or StackOverflow. :-) Thank you for fixing my answer. – Vedran Šego Oct 9 '13 at 10:47

While the reason behind this shot (and any other shot just like this) could be, just like Vedran suggested, a trick to get the other person to believe that you for some reason had to fire your gun at something, or someone, else and must therefore be distracted making it a perfect opportunity for the other person to take off; the reason could also be to make that person believe that you in fact know where he his but just happened to miss. In either case, the person being hunted is unlikely to stay in his current position after hearing a gun shot. While the actual, specific reason varies; the basic idea is to trick the other guy to reveal himself by making a run for it.

Was also what I would have thought. While similar to Vedran's good explanation, I'm glad someone wrote this as an additional answer explicitly. – Napoleon Wilson Oct 9 '13 at 19:20
I feel this is closer to the mark. The shot stirred the birds which covered Bourne's movement in an otherwise loud environment (thick dry brush). The Professor knew Bourne would use this to get into a better position and had no choice but to try to do the same. – David Harkness Nov 20 '15 at 22:49

My view is that the birds when they came back to land in the field would not have landed anywhere near the prof therefore giving Bourne an idea of where in the field he was hiding. The fact that the shot made him move was a bonus.

After Bourne shoots, he is watching the birds to see how they react. When they took off as well, they wouldn't have been around the Prof either. – Steven Jan 15 at 19:02
