Well, also...just because someone did something, doesn't mean it isn't illegal here and now (or wasn't illegal then and there, for that matter). Sometimes people get away with things; that doesn't mean you will if you do the same. "But he did it!!!" doesn't even work on a first-grade teacher, much less cops and DAs.
First of all, I wasn't discussing the legality, at all. Secondly, as you well know, people engage in cross art matches all over the country on a daily basis that are perfectly legal.
