    High light condition with short depth of field means a large aperture and fast shutter speed was used. The fast shutter speed was used to avoid motion blur. However, the focal point is in front of the podium, the whole picture out of focus.

    A modern professional camera can use shutter speeds as fast as 1/8000th to 1/32000th of a second. The AR-15 has a muzzle velocity of 3000-3300fps. The length of the visible trail is heavily dependant upon relative humidity.

    If you want something fucked, it’s that the focal point is in front of the podium. The camera almost always does that, not the photographer. AutoFocus is a touch or half push on the button that takes the photo on a full push. Some security agency probably modified the photo to prevent internet sleuthing and ensure they’d control of the narrative.

    Note that this is only application of basics. It’s not a nuanced or expert perspective.
