Scope out the scene. You'll spot a light fixture mounted on the wall, on the left side of screen. Shooting the light itself, will only break the bulb; Shoot the small hook/ring that
holds the light in place... You'll have to time it correctly, however. Wait until the baddie is on the right (he paces back and forth / left and right), otherwise, you will miss. Once
you time the shot with his walking pattern, the light fixture will swing and knock out the target.
