Do you think that Americans are being desensitized by our government & the Dept. of HomeLand Security to the presence of the military & military vehicles while they are doing practice 'drills' on our streets & in our cities?

Recently the military went from a military base in Maryland to St. Louis in order to have their military personnel ‘practice’ driving around the streets in military vehicles. There are any number of large military bases that have residential streets on which this ‘practice’ could have taken place, so why are they ‘practicing’ in our cities? The responses on the part of the public have run the gamut from enthusiastic support to fears that the government & the military are trying to make an ‘end run’ around the restrictions represented by Posse Comitatus. After all it is almost a crime now to fail to flaunt your Patriotism, especially since the Patriot Act was passed. Considering the increasingly militarization of our local Law Enforcement agencies & their willingness to respond with brutality, & ‘shoot first & ask questions later’ – I am wondering if this is something about which I need to worry? Is this the next step in the ‘Papers, Please’ situation which the people of color in the United States are already having to deal with?
