How am I missing the point? I'd say you are more than I am. I don't give a flying fuck about polygraphs and I'm almost 100% certain you liked a post of mine recently where I explicitly said polygraphs are the junkiest of junk science used in forensics. You use that to dupe Turmp into answering questions under oath, which will roast his ass because he can't go 2 seconds without lying.
I also have a hunch that Turmp puts a lot of stock into polygraphs and would be quite nervous about taking one himself and considering he also can't seem to go more than a few seconds, let alone when being asked questions like if he raped someone, he'd have a very goddamn hard time keeping from getting agitated. He can't respond with simple yes or no, so the moment you start getting "no, she's ugly, I never even met her" followed by a pic of him meeting would be pretty goddamned damning and would show polygraphs don't mean jack fucking shit, so it would undermine using them in the first place.
