Well but I think those instances are like, "wow this dude actually went to jail? how badly did he fuck up?" or whatever. Like, a counter example is like, one person went to jail for the financial collapse of 2008--to the surprise of no one (though, a fair amount of justified outrage). Rich people also frequently pay no taxes, like famously Amazon.
But, I don't think people have a detailed understanding of these things. I do agree they're at best fuzzy about what international law is (I am also fuzzy on it). I just don't understand what's manipulative about it. Like, what are people induced into doing based on the premise that the US follows international law? I think anyone operating in that sphere (international shipping, piracy outfits, aid organizations, criminal syndicates) is probably savvy enough to know the US will just blow you up and lie about it for thirty years.
