So you're basically saying but someone could change the drone in the summary to something bigger and OMG DANGEROUS! Yeah good argument.
The other half of your argument is self defeating. Fires? Yeah because something that may catch fire is really going to kill you. Let me say that again, LiPo batteries do not spontaneously explode. Go get one and throw it really hard into the ground. Yes it may heat up, yes it may eventually catch fire, but if you get burnt as a result it will be because you got some really recessive genes which Darwin postulates may sort themselves out anyway.
In other news someone in my city stabbed someone else because they wanted a cab ride and they felt the cab stopped for the wrong person. Your little old lady has nothing on that, other than a case of the bat-shit insane. So let me commit the True Irish fallacy and say "No true sane person gives a shit". And that can be found by a quick Google search that shows the FAA hasn't done anything about individuals flying yet, only *attempted* to do something about a few commercial cases. So please, share with me your source on the steady stream of phoned-in tips, and the subpoenas and the cease & desist letters. No, Amazon and the guy who filmed the Tornado don't count.
By the way I like how you just pointed to the danger of drones, did you address the rest of what I was talking about? Think about it. With all those damn terrorists about we should ban fireworks and public gatherings. They are far more dangerous than drones.
