Pelosi and the gay escort got into an argument about (who cares what) and when the cops showed up the escort got pissed and smacked him upside the head.
Simple as that.
The story is more simple than that... Paul and his butty left the gay bar at two, went to Pauls trysting place, stripped down to essentials, couldn’t agree on price for services. Butty started screaming he was going to tell Nancy everything, where’s Nancy. Paul light in the loafers grabs hammer. Two local police come to do wellness check and observe two gay guys in their panties arguing. They watch until Butty grabs the hammer and whacks Paul, then grab Butty. Now they, the cops, realize they are in deep doo doo.
Maybe on advice from their Chief, they bust a window with their boot (One plane, not a hammer blow, too small to crawl through, not next to handle) and make up sorry about home invasion. People do not function well under stress and that’s why the story is so discombobulated.
