Because, for whatever reason, I read the article then promptly dumped the information about his arrest in Oxford and conflated it with the arrests at the funeral procession on the way to St. Giles' Cathedral.

Which means it was still not a coronation, it also wasn't a funeral procession, I still think he's boneheaded but not as much as before or nearly as much as the ones in Edinburgh, and none of them should've been arrested (maybe perhaps the one that shouted at Prince Andrew, but definitely not the others).
