I find your post to be absolutely repugnant, and demonstrates an obvious lack of historical context. Like me, he took an oath to defend the Constitution of the United States, not Adolph Hitler.
The purpose of the TSA is not to make us safer. It never was their purpose, and after 9/11 some high up guy in DHS openly admitted that fact.
As far as metrics go, the TSA has never prevented a terrorist attack and has done nothing to actually make Americans safer.
That said, I apologize for my offensive comment. Your son does not work for Hitler.
