I thought that m52nickerson meant it as: "Even a legally elected goverment might decide to break the laws and/or become a tyranny, just like a random person on the street might decide to kick puppies and steal candy from kids." I don't think he ever said that it would be a good thing or acceptable. Just that they could try to do that (I suppose that in a democracy there should be people, judges and organisations to stop them but if you look at history this has not stopped dictator from doing it in the past.)
And I kinda agree with that. Any given day I have the option of trying to get rid of my financial troubles by robberies, forgeries or other illegal activities. But I don't take that option. And seriously, the only thing stopping me is myself. Nothing stopping me from trying that is, my success in criminal activities is another matter since that cold be prevented by the police for example. Just like, if for ecxample, the US goverment would hypotethically decide to imprison people without a trial or torture prisoners or something then their internal safety mechanisms (supreme court, congress, people no longer voting for asshats who support torture etc.) should kick in and stop them. And I suppose soldiers who refuse to obey illegal orders would also prevent such atrocities.
