Have you been watching what has happened over the last couple of decades in the US and UK? Almost all politicians are under the financial (and hence political) control of somebody else, and if they remain too independent their own political parties treat them as too hot to handle and through them to the wolves.
That is not just the case of US but almost every country in Europe/Asia. Political tricks are often emulated across the pond by all of these politicians. You have heard about RIAA/MPAA's impact in music/movie industry in India (and some other countries in asia). All the movie studios and labels owned or in partnership with some of the US based brands (Like Time warner, 21st century fox etc) are forcing to bring censorship on net in order to control their business. As for politicians, we have same situations here, each party has their own agenda and they try to push something that benefits their lobby.
The reason I said there are people who bring this to public is because it is easy to become hero by exposing each other for their acts and gain votes or win 5 minutes of fame. So not only politicians but media and some of the NGO's bring such to public's attention for their own benefit. They get their fame or money from the lobbies and after some time we all forget some of these policies and adapt to it.
As for patriotic act, you can't asses that issue from neutral ground anymore after so much involvement of that country in middle east and almost every other islamic country. If they don't pass that act and let any random tom-dick-harry to pass through their country and do his/her thing then normal citizens of america are in danger. Why? because often terrorists target normal people and not politicians to make their point or to grab attention. Though I hate that patriotic act, it's necessary evil which lobbyist and politicians are pushing because of their own messed up situation and for profit. Soon, America will be under birdcage of their own restrictive policies and fear culture and if not, they'll be targeted by people they pissed off in middle east. And it's not even made-up situation by FBI anymore, to some extent there are groups working to harm united states. Even in India, when 26/11 happened, terrorists were after American and British citizens and they spared people from other countries. That tells me everything about the other side of fence.
Last thought - in any western countries these days if you want to get legislation passed you just cite public safety and terrorism as a mantra!
Not true. Legislation is passed with or without public interest. Legislations are passed to the large extent due to lobby interests. SOPA is the only legislation that was opposed all over the globe due to it's impact on American economy (directly or indirectly) and that's why RIAA/MPAA lobby failed to convince other business lobbies for that act. You know the result right? You're assuming that large percentage of Americans are conservatives and that's why terrorism mantra works and that is far from truth. Many liberals, non-liberal-non-conservative crowd is moving away from these type of claims. You know why ron paul is developing some followings? He wants to legalize marijuna, oppose sopa and every other white-collar issues that are ignored by republicans and other liberal parties. The reason obama won last time because he was *not* bush and people never wanted that war. Obama delivered that and there is no direct signs of war with any country today( though some random clashes do exist but no panic signs). The problem with developed nations like united states is that infrastructure and social development issues are negligible and for that reason politicians create artificial problems like - gays in military, prayers in school, Dream of America as a Christian nation, war with terrorism and intellectual property rights issues.
Do you know Santorum made deal with some random SEO agency(as per SEOMoz) for positive reviews across the Internet. Don't be surprised if tomorrow Google or any other SE gets sold with billion of dollars deal to screen negative reviews for these politicians or even get ISP's to block such websites. That is the future, I don't want to see.
