30 frames a second is standard speed for video. Most new digital cameras today can capture videos at 30fps. The issue is was this photographer expecting something to happen that motion would want to be stopped and closely examined? The second question is shutter speed. Unless someone is trying to capture a super speeding car or perhaps sprinters at the Olympics where inches determine the winner, it's simply not needed. 1/8000th of a second means the photographer was trying to stop motion. The fact that he was capturing 30 fps means he was trying to capture something speeding and have the ability to stop at a very precise spot and also play the sequences surrounding that spot back in slow motion.
The fact that it was broad daylight gives a still photographer the option to decrease the ASA number (decrease light sensitivity) and/or decrease the aperture of the lens. It's like your eye's pupil. When it's bright your pupil closes and when it's darker the pupil opens to let me light in. Shooting at 1/8000 means not much light can get in before the shutter closes so the lens aperture was wide open at F1.6. Being a 24mm lens, assuming the camera had a full frame sensor, was a moderately wide angle. All that means is that the photographer wanted the ability to capture an object moving at high speed and using the fully open aperature to let enough light into the camera and wanting to get a wide area of view to see the object and the area around that object at the same time.
The photographer could have been looking for the perfect facial expression, perfect hand gesture, perfect flag ripple in his defense. Conversely, it would have been totally consistent to have the camera set like this to catch the president's head explode and see the bullet entering and exiting. It's not unusual for professional photograhers on assignment to try their best to capture just the right cover photo for a magazine for example and burn through thousands of images trying to find the exact perfect one. Often, they are in competition with lots of other photograhers doing the exact same thing. It's why you often hear the motor drives whirring at press conferences or paparazzi trying to catch that perfect crotch shot as a starlet is exiting the back of a limo.
No way to tell what the exact motive of the photographer was however. More evidence would be needed to prove he was looking for a specific thing like a head exploding.
So let's see, ISO 50-200 is 2 stops. A normal bright day without snow would typically be F16 with ISO 200 or F8 at ISO 50. Both of those would be accurate with a shutter speed of 1/250. So, assuming F16 was correct with ISO 200 @1/250, then F8@1/500, F5.6@1/1000, F4@1/2000, F2.8 @1/4000 and F1.6@ 1/8000 would be accurate. If working with ISO 50 @F8 @ 1/250 was accurate then F5.6@ 1/500, F4@ 1/1000, F2.8@ 1/2000 and F1.6@ 1/4000 would be the limit. With some brighter scenes and digital stretching 1/8000 is possible. But with any clouds and possible shade it's less so. What's the point? Each of the above settings would give appropriate exposure but only the fastest shutter speed would stop high speed, like a bullet. Interesting that he chose to go the the limit of shutter speed when other choices were available.

Who uses or says ASA anymore?
As stated multiple times this has been posted, he was also capturing the flag in the background.
With an ISO around 50-200, an aperture at 1.6...a shutter of 1/8000 is an appropriate approximation for proper exposure.

If you want the crowd to be a blur why would you shoot above f2.8 or f4? Trump is the focal point. He also wanted to capture the flag.
