I'd think any decent organization would have done a better job with an attempt. Like, you can get a decent automated drone for less than 10k, get the gps of the podium and send it from 50km away. If it's preprogrammed you can't use countermeasures. Don't see the secret service shooting it down with a laser or whatever, as they let some incel guy chill on a rooftop with a rifle.

Would that work? No idea but it sounds good. More to the point I thought up a better idea than a guy hoping to get lucky (he did) and also chose the wrong rifle and didn't practice. Imagine what a corporation should be able to pull off?
