It's kind of weird that all of the responses here berate England and say that George's wife should have had a gun. Yes, the wife couldn't defend herself with a gun because of strict laws there on gun ownership. But people selectively ignore the fact that the attacker also could not use a gun.
Knives are deadly weapons, but they do not compare to guns. If all three of these people were armed with guns, it's likely that all three would be dead. As it is, all three were only slightly injured.
England's laws prevented the attacker from using a gun. By comparison, John Lennon was shot dead by his attacker. Guess where that happened? Yep, good old US of A.
Thank God we have guns here! But if you're a Beatle, the moral of the story is: Stay in England where your assassins have to use knives.
