Norm Mineta and the TSA

With all due respect to Michelle Malkin, she and others are calling for the resignation/impeachment of Norm Mineta, I think they are wrong.  They aren’t thinking big enough.  They should be calling for the abolishment of the entire TSA.  Show me again where the U.S. Constitution says the Federal government is authorized to stick their nose into this.  Show me again where Mineta Minions are exempt from the 4th Amendment.
