A lot has changed since 9/11, mostly all for the worse. When I took the commuter train from Baltimore to Washington, D.C., on the morning of Aug. 7, 2007, “Big Brother” knew I was on it, since an ID is needed to buy a ticket. When I got to D.C., “Big Brother’s’” cameras watched me get on and off the Metrorail. When I tried to videotape a demonstration at the DOE, a security guard threatened to confiscate my camcorder and to put me “in handcuffs!”
