It's late, and I'm tired, and I have no idea what point you think you're proving… but if you want me to go away and Google a whole bunch of links where Pat describes himself as the "co-creator" of Judge Dredd or, at the very least, allows articles to stand* where he is described as "co-creator of Judge Dredd" then, fine, I'll see you tomorrow.
*Given that he's gone out of his way to make at least one blogger/podcaster correct their blurb to ensure that he was described as "THE creator of 2000AD" then it's fair to infer that he's happy to insist on corrections to creative attributions so that they meet with his approval.
