I can't speak for him. But, from what I have heard him say (in the recent interview with Sean Hannity) I don't believe he wants you disarmed. Does he want just anyone, no questions asked, to have guns. No, I don't believe he wants that, either.
I think that as mayor, Rudy Giuliani could do nothing about the 20,000 gun laws in America or the supreme court's decisions that let state and local governments regulate guns (thanks to that conflicting phrase in the second amendment, "a well regulated militia").
And I think Rudy Giuliani believes that laws that are appropriate in one environment may not be in another. (I got my first gun permit in rural Northern California. It involved a yearly $12 fee and a talk with the local sheriff. When I moved to New York City with it's 8 million people and it's violent street gangs, it was near impossible to get a permit -- and that was before Rudy became mayor.).
No, I don't believe Rudy Giuliani wants me disarmed (I'm a peaceable, law abiding citizen), nor am I willing to blame Rudy for the sorry state of gun laws in America. I think he just wanted to bring the murder rate down.
Perhaps, I do disagree somewhat with the mayor about guns. But, it's hard to disagree with a mayor whose actions prevented over 1000 gun deaths in New York City each year.
As mayor of NYC, Rudy sought to have his standards imposed nationwide. He has never repudiated his actions nor apologized for them.
