From the WSJ article I mentioned: “ Federal law prohibits the military from shooting down drones near military bases in the U.S. unless they pose an imminent threat. Aerial snooping doesn’t qualify, though some lawmakers hope to give the military greater leeway”
2) as you probably know, the pilot doesn’t really guide the missile…calling the pilot an idiot just clearly shows you have an axe to grind. Also, it’s not like the seekers are calibrated to take out balloons.
3) regarding EW - the tech is obviously still evolving and not always deployed “ U.S. officials said they didn’t know who operated the drones in Nevada, a previously unreported incursion, or for what reason. A spokeswoman said the facility has since upgraded a system to detect and counter drones.”
Also, it is certainly possible to harden drones against EW as is being done in Ukraine on an evolving basis
