The funny thing about a knee-jerk reaction is that it often comes back to haunt you. Graeme Swann must have probably realised that by now. And although the Trent Bridge Test gave us so many fascinating cricketing moments, it's not possible to step away from the Stuart Broad incident yet. If anything, it was the one dish that spoilt an otherwise outstanding buffet and an outstanding advertisement for cricket. Not just Test cricket, but all cricket.
The mind goes back to many incidents, but three in particular will, hopefully, help me explain my position on this.
The first is from March 2012, when - in a game I didn't see but read about - England XI were playing against a Sri Lanka Board President's team in Colombo. Dilruwan Perera had, by all accounts, sent a fairly meaty edge off James Anderson to Andrew Strauss at slip. The umpire was unsighted and Perera refused to walk, which meant he was given not out.
