That's a good question. I honestly have never seen Paul or any of the others talk about John's death. To stick up for Paul, in his position I'd think it has to be nearly impossible to publicly be torn up over anything. Reporters are hell, and there's only so much you can stand. I think Paul had to be strong because he couldn't get to the point where the reporters could just walk all over him. We may not have seen it, but honestly, he's not heartless, John and Him were amazingly close for so many years, I'm sure the fact that John died was very hard for him to handle. And many people have different strategies for coping with loosing someone, maybe Paul's is to close up, you know, act tough so no one sees how he's really feeling. I dono, its all my opinion, more like my guessing what's going on in Paul's mind. And about how John would have acted, well, John was a very passionate man who spoke for what he believed in. He also said he had great defenses because he was the type of guy who didn't know how to cry. So I'm not sure you'd see John openly torn up over it either. I can imagine John would have started something for gun control and tied it in with Paul.
The only reason people are so busy with Paul's responce is because people knew that by the time the Beatles split John and Paul had their share of arguments, and anger towards each other, and so people take it upon themselves to question Paul's reaction.
