Expect a ******* broken arm!

So the game of cricket plumbs new depths.  The Australians pretty well invented "sledging", but originally it was no more than relatively good-natured banter aimed at disrupting a batsman's concentration, but now it's turned into something decidedly more nasty designed to put a batsman in fear of physical harm.  How long do we let this go on? Because it's not going to stop by itself - it will only stop if players and teams are made to realise that it's not worth it, and that won't be achieved by handing out fines, but by penalising teams where it hurts - by docking runs or wickets.  That's how I see it anyway.
