Well, I wouldn't say we're fullblown there, or even that there's a steady progression.
omgz department of HOMELAND security. ohz noes.
Now, there is police brutality, and the TSA can be dicks, but that's always been around. Some people just know how to react better to police brutality (See:Athens)
However, there is the concern of wiretapping. Bush raped us on that one, and Obama has yet to repeal the Patriot Act or any other wiretapping concerns. So I think it's there to stay.
There are endless wars that can be used to abuse rights. Greatest example: War on Nouns. Drugs, Poverty, and Terrorism will probably always exist in some form, and I believe prohibition is wrong.
But: We lock people up for smoking plants and doing what they want on their own time. We overlook the fourth amendment rights with things like "probable cause" "no knock warrant" and other shenanigans that ends up getting people brutalized or the wrong house is raided and innocent people die.
Terrorism is a criminal matter, and we got ourselves into two fucked up quagmires and dragged some allies in. All in the name of fighting a specific type of crime. We've conveniently created a potentially endless war that all kinds of people around the world can profit from. Defense contractors get to shaft the government, and all kinds of immunity, politicians get to be "tough on terrorism" and increase security and surveillance, terrorists get us to send foreign soldiers delivered to their own backyard so they can keep killing people in the name of freedom fighting or holy war, so they have us where they want us.
In addition doublespeak is very close to reality, because people do manipulate language. Ever heard the terms "pro-life" (anti-abortion, like to shoot up and bomb clinics), "enhanced interrogation" (torture), "fair and balanced" (so far right Hitler could have owned it) or "patriotism" (blind nationalism)?
"Two minutes hate" is unlikely, but having seen some of the reactions to Obama when he was elected I could see it in a very extreme case.
In addition we do sort of have that whole "We were never at war with..." mentality. Saddam propped up by us, Osama was one of the fighters we used to supply, Ahmadinejad offered help in Afghanistan (for selfish reasons) and we put him in the "Axis of Evil".
So, in summary, it's just a really exaggerated version of real life things portrayed to make us check ourselves.
