Agreed.
If Given and Murphy are the answer, then it must have been a really stupid question

Given seemed to be saying that Arsenal have cheated in a similar way in previous games and got away with it, therefore West Ham should be entitled to cheat in the same way. That's really not the way football works.
In relation to the ridiculous stuff in the box at set pieces, which was probably started by Arsenal, but now done by most teams, the answer is simple. The Ref needs to give 1 warning. After that, the ball is deemed live even before the Corner is taken. A couple of Penalties and a Sending Off and, as if by magic, all this nonsense stops.
And that isn't new. I remember that certifiable loony tunes Jens Lehman being sent off in exactly that way. Wrestling, blocking off the keeper etc is (or should be ) no different to kicking the ball away or preventing a quick free kick.
Off to watch Spirs v Leeds on Sky. I've warned my Wife that my language may get a bit, er, industrial...
