"As much as you don't like it, the doctrine of implied consent is a long-standing and valid principle resting on sound legal and practical grounds. The way airport security is currently conducted may not be effective, but it is not unconstitutional and not un-American in that it does not go against any founding or guiding principles of the United States."

It may be constitutional, but it is still definitely un-American. I object to ALL warrant-less and probable-cause-free searches, not just what goes down at airports in the name of illusory "security". It sickens me that roadblocks and other random searches are permitted in this nation in the name of safety.

Just because something has been ruled constitutionally valid does not make it "American". Slavery, non-universal-sufferage, Prohibition, etc. were all validated by one or more incarnations of the Supreme Court. Would these be considered "American"? Only in a historical sense, not in any principle about which we should be proud sense.
