I am sure someone would miss the person disappeared by the government. Unless you believe the government is disappearing people along with all their friends and families"
No need for that, of course friends and family will miss the missing person, but what can they do? File a police report? They can't undisappear him. Who would ever know? There is no guarantee that the media would make a big thing out of it.
"Whether this does or does not happen can only be guessed at by looking at general behavior"
And here is the main problem. You can't prove the government is actually killing or disappearing people because of their political stances so you generalize and try to justify your statements and opinions using by trying to predict future behavior.
As I said, I am not trying to prove anything. I am only saying that whether disappearances happen can not be known for certain. You can only make guesses based on e.g. missing person cases and general government behavior. The extreme exception is of course if is a disappearing action somehow goes wrong and becomes public - but that seems unlikely in any case.
Oh and did I mention gitmo, the lack of due process, the governments ability to hold citizens in prisons indefinitely when they invoke all those nice patrior act laws? All of that doesn't count as disappearing people?
And if you need to use the Ruby Ridge incident to support your opinion that the government is killing political dissidents, journalists, and even leakers is weak. The FBI was going after a white supremist
You and I may not like white supremacists, but that does not make it ok to just go out and kill them either. If the government is ready to do that, there is no reason they wouldn't act similarly with other unwanted persons - except perhaps for public perception. But we have all seen how much they care about public perception these days.
