From an article in The American Conservative:

When Bush came to the Pittsburgh area on Labor Day 2002, 65-year-old retired steel worker Bill Neel was there to greet him with a sign proclaiming, “The Bush family must surely love the poor, they made so many of us.” The local police, at the Secret Service’s behest, set up a “designated free-speech zone” on a baseball field surrounded by a chain-link fence a third of a mile from the location of Bush’s speech. The police cleared the path of the motorcade of all critical signs, though folks with pro-Bush signs were permitted to line the president’s path. Neel refused to go to the designated area and was arrested for disorderly conduct; the police also confiscated his sign. Neel later commented, “As far as I’m concerned, the whole country is a free speech zone. If the Bush administration has its way, anyone who criticizes them will be out of sight and out of mind.”

At Neel’s trial, police detective John Ianachione testified that the Secret Service told local police to confine “people that were there making a statement pretty much against the president and his views” in a so-called free speech area.

The feds have offered some bizarre rationales for hog-tying protesters. Secret Service agent Brian Marr explained to National Public Radio, “These individuals may be so involved with trying to shout their support or non-support that inadvertently they may walk out into the motorcade route and be injured. And that is really the reason why we set these places up, so we can make sure that they have the right of free speech, but, two, we want to be sure that they are able to go home at the end of the evening and not be injured in any way.”

Attempts to suppress protesters become more disturbing in light of the Homeland Security Department’s recommendation that local police departments view critics of the war on terrorism as potential terrorists. In a May 2003 terrorist advisory, the Homeland Security Department warned local law enforcement agencies to keep an eye on anyone who “expressed dislike of attitudes and decisions of the U.S. government.”

One of the most violent government responses to an antiwar protest occurred when local police and the federally funded California Anti-Terrorism Task Force fired rubber bullets and tear gas at peaceful protesters and innocent bystanders at the port of Oakland, injuring a number of people. When the police attack sparked a geyser of media criticism, Mike van Winkle, the spokesman for the California Anti-Terrorism Information Center told the Oakland Tribune, “You can make an easy kind of a link that, if you have a protest group protesting a war where the cause that’s being fought against is international terrorism, you might have terrorism at that protest. You can almost argue that a protest against that is a terrorist act.” Van Winkle justified classifying protesters like terrorists: “I’ve heard terrorism described as anything that is violent or has an economic impact, and shutting down a port certainly would have some economic impact. Terrorism isn’t just bombs going off and killing people.”
