Umpires should be given red-card sanction

In the Sunday Telegraph Scyld Berry says that Steve Harmison's shy at Inzamam-ul-Haq could have resulted in something far worse that a run out, and warns that the time could come when players resort to fisticuffs to resolve their differences, and that umpires should be given red cards to deal with such a scenario:

A fielder will either think twice, or else will aim at the stumps with the maximum of care, if he risks being sent off the field for the rest of the innings because he has hit the batsman with a none-too-careful throw: that obnoxious practice introduced by the Australians in Steve Waugh's time.
