The first time someone uses an impossible to trace drone to take out a law enforcement officer in the US is going to change everything.
The status quo has been that law enforcement can operate in an openly corrupt way with impunity because they can absolutely positively find someone who fights back.
But all the pieces are there for people to fight back with equal impunity. The technology is mature and deployed and has been tested in Ukraine and Syria for several years now.
It's just a matter of time before someone takes out a corrupt cop or ICE official and they get away away with it.
It will have a chilling effect on this kind of behaviour.
