Right....so what evidence is that? We don't have any confirmation on who that is, and looks different than the guy who showed up on the sidelines of a michigan game the next day.
And even if it is him....so is the argument that great harm was done because a guy, with no recording equipment, stood on the sidelines? You can convince me there's some advantage to recording the signs, you can't convince me that there's great advantage to sitting on the sideline in person of a fully recorded football game.
