At least football doesn't have to cope with this violence

Well at least football doesn't have this to contend with very often. What's astonishing is that the English sports pages are dominated today  by the brainless racist chanting of football fans while this piece of thuggery is buried. You will need to watch the replays before the violence is obvious.
At least the broadcasters, including John Inverdale, were outraged, and Eddie Butler wrote an interesting piece about the All Blacks and the dark arts they have always employed.
But on the whole, the papers are not interested.
There's a vast amount of hypocrisy in rugby, which is held aloft as an honest, if violent sport, but this has gradually disappeared since the onset of the professional game. Various rules - walking players back 10 yards, calling the ref "Sir" etc - have been held up as an example to football, but we hear these calls less and less often. Dissent is becoming commonplace and criticism of referees on the sports pages is as strident as it is with the round ball game.
Just imagine the national crisis there would have been if someone had done this to an England footballer during an international match against Italy, for example. The miscreant - in this case All Black hooker Andrew Hore seen punching Wales' Bradley Davies unconscious after just two minutes and putting him out of the game - would have been locked up in the tower by now.
