It’s very easy to take down a drone. And I don’t mean shoot it down with an assault rifle. You could even take it down with a sophisticated slingshot once it’s in a low altitude. And in order to tase or spray someone it has to get really low. These things are very slow and not that agile.
For sure. Laserpointer to blind it, jam gps to confuse it...

For tasing, sure. And for spraying an individual in the face. But if we're talking swarm-based crowd control, there might be other options. Anything bad that drops down (say 1000 minature cs-cannisters -- effective even if a few are "thrown back", other gas that is heavier than air, perhaps created by blending two components "on board" the drone, perhaps forms of acid or irritants liquids that are arezol'ed with pressure... audio-attacks...
In fact, swarm based drones might even be hard to take out, if they could rely on low-bandwidth, near-field comms, such as IR, lasers, (directional) ultrasound or whatnot. Not even sure if there's much current research in combining directional ultrasound with the type of advanced coding that is used for high-bandwidth radio short-wave/microwave comms.
You’re talking science fiction now. If it becomes so small as a fly how on earth would it be energy sufficient? With a battery? And that battery will hold enough energy not only to keep it flying but also to provide for a taser that could incapacitate an individual? And at that size it should also carry some communication infrastructure to receive instructions from a command center, a gps, and a cpu capable of running face recognition or even detect movement patterns because otherwise you can’t have efficient crowd control. Sure, in a couple of generations we’ll get there, but not in the immediate future.
