Would Beckham go to jail?

My wife has raised a very interesting question about the alleged plot to kidnap Victoria Beckham.

Let us imagine that an armed intruder has entered the Beckham residence in the middle of the night. According to the BBC:

David Beckham said he would protect his family

Mr Beckham is a very fit athlete. Let us suppose that there is a struggle resulting in the death of the intruder. Would the police charge Beckham with murder? If they did, and especially if he were imprisoned, there would be a enormous public outcry. I have little doubt that it would be led by Tony Blair assisted by the massed ranks of New Labour. Hypocrites
