I was assured by the internet, I was paranoid, blah blah safety...
Then a few weeks ago something about Minnesota and ICE making drones illegal to fly or something...
The weird part is that, in that 15 years, I've become more moderate and pro-democratic rule of law... but I was right about my previous concerns. Not that I believe in the Justice behind them anymore.
And that radio jamming no longer neutralizes that threat.
The far more likely explanation is that they just don't want people filming them. They can't legally stop someone with a cellphone from filming them, but that hasn't stopped them from using up-to-lethal force against observers. On the other hand, you can't exactly beat a flying drone into submission, so the obvious move is to observe using drones instead.
Luckily for ICE the FAA already has the mechanics in place to criminalize flying drones in certain places, so with their magic "no drones anywhere we operate" NOTAM they can now punish observers with a year of jail time.
