If you're attacking Mr. Tymon or blaming him in some way for the BBC's firing of Clarkson, you are an idiot.
He didn't report the fracas, Clarkson did. Like an evolved homo sapien, he didn't fight a coworker over food. He never asked the BBC to do anything about the incident.
As he has been prone to do in the past, Jeremy Clarkson shot his own dick off and brought about the end of Top Gear. It is no one's fault but his, and I would bet he will say so when he gets a chance to speak publicly about it. I'm a huge TG fan and very disappointed by all of this, but let's not make a martyr out of him. He has not been wronged. If your boss punches you, he should be fired.
