I’m not sure how many people realize this but with some of the commercially available drones, it would be very easy to send these drones into a crowded stadium. It wouldn’t take much of a “payload” to create utter havoc.
Drones seem to have a lot of downside to them. I wonder how it will be possible to stop the threat of the bad guys using drones in ways such as you suggested.
Doesn't sound very easy or practical, and politicians would still do nothing. An easier hypothetical scenario is when experimenters use drones on antifa and lib protest gatherings. They would easily panic in utter havoc and chaos. Only then would lib politicians make preparations to curtail use of drones.
The same can be said of the R/C aircraft that had been sold in hobby shops for years (some can be truly massive). The main difference now is that drones are ready to go out of the box.
