I followed the link to the sad saga of Israel Rondon thinking it was about the "sovereign citizen" who was squatting in people's houses when they went on vacation, but no, this was a different sovereign citizen.
This may have been false sympathy since it looks like Rondon was on a downward trajectory. I am guessing he wouldn't have received mental health treatment gracefully even if it had been offered. So he got shot in the head.
People like Rondon are very difficult to know what to do with. Shooting them in the head seems both inevitable and less than optimal.
Not all sovereign citizens are dangerous, but the publicists who feed their fantasies are.
Whatever, easy access to firearms made everything about Israel Rondon worse than it had to be.
The gun nuts have a lot to answer for.
