I found a link to this story at a business site. It describes a visit by federal Homeland Security Agents to a college student's home after the student requested the library order a book for him that was research material for a political science class.
Now, this action was taken under the auspices of the USA Patriot Act, which Senator Russ Feingold of Wisconsin and others have succeeded in blocking until respect for the civil liberties of American citizens (like this student) are given more protection.
The Bush administration has used the war on terror to launch a campaign to essentially shred the constitution in the name of war powers for the presidency. This is not what this country is supposed to be about. Read the story about this college student and understand what this argument is about.
