Here's something I think is worth talking about.
How do you feel about the idea of effectively quarantining the President from protestors? Do you think he is entitled to only have supporters in the crowd when he speaks?
Do you think the protestors rights have been violated? I know 2 people who will undoubtedly say, 'No, because they still got to protest inside the FSZ.' but what makes the supporters privileged? Why does content determine whether you get to stand close by to hear the President, or a third of a mile away?
I don't think you can really justify doing it by saying it makes the President more secure either, except perhaps from random kooks too zonked to know better.
