I know here is also where there is a split on what everyone thinks the government's true intentions are. I think this is where the Occam's razor principle applies, where among competing theories, the one with the least assumptions should be followed.
So is it that because there actually exists terrorist threats across our borders and inside the country, with bigger cities especially vulnerable, that these municipalities should be prepared for all contingencies in case of a bomb/hostage/other terrorist situation, and where these training exercises are good to understand the logistics inside a city center which can't be replicated elsewhere?
Or is it that there is some vast conspiracy involving tens of thousands of people that had been set in motion for many years, where the government is looking for the opportunity to brainwash the populace in order to turn them into a police state, convincing the military and police alike, who would otherwise be extremely loyal to Americans and fight for the citizens and their freedoms over any threat, but suddenly convinced to betray that, and involving other secret leaders who have set to destroy the economy in multiple industries in order to turn this country into financial chaos, disarming them in the meantime, and then being able to have the infrastructure and power to control over 300 million people spread across tens of thousands of square miles...etc...
I just don't get the sinister vibe, even if those in charge are incompetent, arrogant, and prone to delusions of grandeur and infallibility. There is just no way a takeover is possible logically or logistically.
But for those arguing that "see, if they do it to him, they'll do it to us," I'd say you guys shouldn't worry unless you murder 4 innocent people in cold blood, two of them police officers, and taunt them with a manifesto and media packages you send where you admit to your revenge plot. Because then you increase your chances of your civil rights being violated.
