To a degree he does have previous and it could be a good way to make him stop acting like such a retarded idiot on the field.
How often does his sweary behaviour or daft thoughtless revenge fouls get him bookings or even red cards in crucial matches. At this stage it doesn't look like he's "learning" from Fergie or from experience so maybe a ban isn't a terrible idea.
However, consistancy, you see REF'S swearing at players, you can see ref's, maybe jokingly saying f off to players when they are asking for a freekick/penalty/getting in their faces, its not particularly often.
But lets face facts, swearing is a NORMAL part of our language, we all swear a bit more than usual when in pumped up, andrenaline rushing situations, so its retarded to go after people for perfectly normal language. We can pretend no one ever swears, ever, or be truthful and accept its not a huge deal. Though Rooney was specifically swearing into a camera, and its not the first time he's done that "at" the fans in that way.
Frankly I'd prefer he gets a ban and learns his lesson, eventually, than does it in the Euro 2012 final..... or more likely the group stage.
Then again a ban for the ridiculous elbow would have given him much the same lesson, been a bit more consistant with extra stupid challenges off the ball getting bans, and been a fairer decision.
FA= stupid, Rooney = stupid, two stupid decisions don't make a right one.
