"For my friends, everything; for my enemies, the law" - Óscar Benavides, former president of Peru.
This can only be true if the law is broad and relies on "good faith". This is why laws and court ruling are often narrowly tailored, to prevent a precedent being set that will open the door for future abuse down the road.
>Investigative agencies are going to be able to investigate people. So supposing that the "US government can ... investigate Richard Spencer ... based on a web post" isn't a compelling argument unless your goal is to completely reject the concept of government. As has been often said, you can get a grand jury to indite a ham sandwich.
I suppose I could have fleshed out this argument a little further, a distillation of my point would be that "investigations" are carried out with little or flimsy evidence as a pretext to go on fishing expeditions to find something, anything to actually charge the person with.
>we need to neuter the concept of sovereign immunity I wish we could get the government to hold themselves accountable, however they would need to pass a law to override the concept and they do not seem to be in any hurry to do so.
I am not attempting to say I told you so to you, nor normalize the situation. I disagree with your assessment that there ever was a "better time" and invite not only you but everyone to stand against bad laws and practices no matter the letter after the name.
