Journalism professor Jay Rosen, who attended the Democratic national convention, says the "great overlooked story in all the reporting" was the heightened security situation. "It was in your face, nonstop, in thousands of ways inside what was called, in military terms, The Perimeter," Rosen writes. "It came lunging at you as you approached the site and enveloped all when you were on site. You could have your credentials checked twenty times on a single trip from the ground floor to your seats. ... It was telling us that we live in a different world than the last time there was a political convention. ... What was all this security about? And who authored it? Ultimately, Al Queda did. ... Al Queda also came to the convention."
