Good points. Your answer would pass the systems design interview and mine would not.

  A laser however... probably works for this scenario. But even then, there’s a required dwell time, and more sophisticated terrorists would adapt to using ablative skins, or maybe even materials transparent to the laser wavelength... anything to increase the required dwell time and overwhelm through sheer numbers.

    Perhaps the best way would be jamming or hijacking the signal. You could essentially "remove" huge groups of drones at a time.

      In order to do that, the electronics inside the drone would need to be susceptible to the electronic noise. Sure, RF shielding from a military grade perspective is difficult, but for this purpose, copper paint surrounding the electronics enclosure may be sufficient. With GPS denied, inertial and visual navigation would be required. Inertial navigation quickly succumbs to accumulated error, but if GPS signals are stopped (jammed) just a few minutes before impact, INS will probably work, given a calm atmosphere, there won’t be much noise inducing turbulence. Visual navigation is much harder, but the advances in machine learning are making this problem trivial. RF interference is likely the best defense, as quality RF shielding is difficult, especially at extreme frequencies.
