It would be convenient to keep the word "totalitarianism" forever connected with the very specific practices of Nazi Germany or, say, Stalin's USSR, and only those. Unfortunately the word and the practice existed way before and will continue to exist in the future. And there's not just a single form of it.
One can spend all his life between home, office, some cosy restaurant or cafe, friends house, and never understand anything that's going on in society at large, if he's so inclined. Especialy if he's on the upper echelon, e.g not a black, latino, native american, or "white trash", so he doesn't get to transparently see the structures of totalitarianism in a day by day basis.

to cities built for exclusion and closing down of public space: http://www.amazon.com/City-Quartz-Excavating-Future-Angeles/...
to the privitazation of prisons (and the highest incarceration rate of the world by far, surpassing even Stalin's era Gulag percentages when it comes to blacks): http://www.amazon.com/Punishment-Sale-Private-Business-Incar...
to the dwindling middle-class (which is, when it exists, the real pillar of democracy): http://www.amazon.com/Servant-Economy-Americas-Sending-Middl...
Add mass surveillance, three-strike laws that resemble 19th century ethics, the concentrated control of mass media, constant external war, etc etc and you have quite a potent mix.
he talks about various aspects and how those incidents were relatively rare, and militarization has not been happening all that much because of outgunning, but rather government incentives for the War on Drugs and measures designed to have closer coordination between the military and police forces.
Makes for very depressing reading.
