Protecting you from Al Qaeda and porn

There are those that say it's ok for the government to eavesdrop on us 'for our protection'. There are those that say "if you haven't done anything wrong, you don't have anything to worry about". Well, this little story makes for interesting reading. It seems a library patron was viewing some racy material on a web site when he was confronted by Homeland Security goons, and told that he couldn't' t view those web sites.
Now one might reasonably argue that viewing porn on a library's computers should be restricted because it's not private, and other patrons might be offended. I can accept that, but it's the library's responsibility to determine such policy, not the Department of Homeland Security. This illustrates why privacy laws are important. Something needn't be illegal for a person to want it kept private. It's not a stretch for the DHS to monitor what web sites you view at home.
