That's one of the big things here and I totally agree with it. I did originally think there was some kind of connection between trump and Russia. I honestly could not believe for a moment that anyone would vote for him, regardless of what people thought of Hillary. And Russian agents somehow manipulating the results made so much sense.
Of course now I find it doubtful, EDIT:as baffler said, if there was something, it would have been found by now,[/EDIT] but what misko says is pretty much one of my biggest arguments against trump at this point. He's ACTING guilty, wether he has something to hide or not he's making people very suspicious. It's like lawyers saying to never let a police officer search your car, or answer any questions without a lawyer present.
Sure it's good advice, but when you know for an absolute fact that you have nothing to find, nothing to steal, and nothing to be worried about incriminating yourself on, it's a good way to become a primary suspect of whatever they are searching for, and may just mean you have a warrant to deal with farther down the line just because you refused a search. Trump may or may not have anything to hide, but he's essentially refusing a search, and sure while he may be able to do that. It looks sketchy as all fuck when there is already a mountain of circumstantial evidence against him.
Trump may not be guilty of collusion of Russia, but I can almost guarantee he's hiding something that might turn up if people keep investigating the way he's acting.
