While we probably agree on many of the topics you just mentioned...what does it have to do with a security exercise that DHS is doing in Austin? The Feds have run similar exercises for decades.Specifically, if the Federal government did not:
-have a huge domestic spying program aimed directly at our 4th Amendment rights,
-have government mandated healthcare looming forcing individuals to engage in commerce in direct violation of the Commerce Clause on the Constitution
-have a HUD program attempting to socially engineer the racial balance of my community
-have a near 100% debt to GDP ratio (think austerity trigger)
-sell guns knowingly to Mexican drug cartels
-arm radicals across the Islamic world
-view those who value and understand their rights as a threat
If they'd back off and stop doing these things and more and stop being such creepy pukes (or we educate the masses to value their freedom and elect people who understand and respect the Constitution), then I'd back off.
