I watched a video by Botgrinder on YouTube called “you can’t mini whoop the president” or something similar, where he was messing about with an fpv drone at a Kamala rally. Turns out that the Secret Service won’t let you buzz her with a small drone for fun, and if you stand around in fpv goggles they’ll come and give you some grief. He wrote a very funny ai country song about it, worth a watch. However, he didn’t say much about jamming, it was being stood about in the goggles that got him I think. I’d assume that the Secret Service’s jamming is a fair bit better than the Russian’s, but the way the Ukrainian drones have been dealing with that shows that jamming only does so much - if the drone is falling toward the target on an essentially ballistic trajectory, jamming it won’t do jack
