The propaganda answer is terrorists. But at what price? At the expense of our constitution and our liberties? Then are we safe anymore? When you destroy the constitution you have ceased protecting - you're just destroying under the guise of protection.
Once our government has so thoroughly shredded the constitution - what freedom will be left?
Many things can be done under the guise of protection. The KGB, SS and Gestapo were notorious - in fact it was their modus-operandi to destroy personal lives under the guise of safety. But then, who are they protecting? Us - or them?
The KGB was protecting its self from the people because freedom was its enemy. Freedom is an enemy to terrorism as well. But unfortunately we are being lied to and the threats exaggerated and I haven't seen any of the terror threats raised or alerted - so - now we have "gate-rape" going on.
Catching the terrorists should be easy - start in New York with the political terrorist building his Victory Mosque. Quit lying about fundamentalist Islam not being a threat to us. Make them swear an oath to Allah that they will not attack us - that's one they won't violate and then if they won't take an oath - then lock them up. Otherwise - we're too stupid to deserve freedom and we will have it coming to us and can blame no one but ourselves.
