I don't have a problem with on field banter and sledging, and Anderson gives as good as he gets. As long as it doesn't cross the line it's fine.
What does concern me is the Australian media. England seem to have walked straight into a storm from day one that seems to be bordering on hatred. Yes again our media have proved themselves in the past to be far from angelic, but the treatment of Trott is indefensible. Here was an opportunity to raise awareness of mental health issues, but instead, they decided to mock the man.
