so if it was you in a bar and someone punched you, you would be fine with us raising a petition to get the other bloke out of trouble.
No thought not. 
Ever since the falklands / Argentina show all respect has been lost for that program and producers.
Get rid.
1) Still no facts to say he did even punch anybody.
2) Multiple people have denied that he ever punched anybody.
3) They were all drunk and so you have no idea on what the producer said to Clarkson or how he acted.
4) The producer looks fine, so if he did punch him it's not exactly life threatening or serious.
5) May say's its been blown out of proportion.
It's the most entertaining show the BBC has and Clarkson has a connection with his audience that noone else has.
Oh and yes if it was me i'd deal with it man to man with him behind closed doors instead of making millions of viewers suffer as a consequence.
