You're correct on the need they feel to do these drills - consecrates our necessity to keep our guns. It makes us all guilty of something we've never even been tried for - being a "terrorist". We're watched everywhere we go, our email is spied on, phone calls monitored, searched when we go into "official" government buildings or airplanes - we're not FREE. We are prisoners of our own making - we have allowed it - we do nothing to stop it.
The price of freedom is eternal vigilance. ~Thomas Jefferson
“It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie...the greatest enemy of the State.” ~Joseph Goebbels
