Making up false 'disorderly conduct' charges and threatening to arrest because he called him an asshole has been ruled on and it's not a valid reason to arrest someone.  It's freedom of speech.  And it's why they didn't arrest him.     Act polite, don't do dumb illegal shit and you'll never have a problem with them.  He didn't do anything illegal so your plan obviously doesn't work.
