The reason americans are suspicious is because of things like the Patriot Act being used on people in the USA to treat less severe criminals more like "terrorists" and as a bypass to their civil rights. In the beginning it was promised NOT to be used like that.
The reason americans are paranoid is a history of abuses like that.
Look up CARNIVORE and ECHELON as well.
The thing is is that the government is made up of the same cross section of people as anywhere else. we've got the majority of people just wanting to go to work and come home and live and let live, our people that sincerely are there to do good and not abuse the system. we also have our share of crazy tin foil hat people and evil fear mongering "every ayee-rab is a TERROR-IST and will killz you all" types.
US americans are paranoid because it is always the crazies or the fear mongers that propose and muck around in these systems to use them to their own ends. while these things do get used for good, they are also frequently abused. Also, systems with systems that have control or monitor almost everyone, it is easier for an abuse to exert a lot more leverage or do more damage than isolated and unrelated systems that don't directly interface.
Here is an analogy:
If we get our water from a bunch of places and one of them or some of them were tainted/poisoned, some of us would get sick or die unless we found out beforehand (unlikely we'd know all the spots or find out before SOMEONE drank it first).
If we all got our water from one place, so many more people would be sickened or die before we found out (assuming we did not stop it first, which is unlikely to be 100 percent successful all the time).
Another problem with these layers of security is that they only stop the less skilled people, while creating a market for the more skilled people to sell to. anyone can ALREADY go on the internet and buy magnetic card readers/ writers, magnetic badges, RFID readers and such commercially; So what is to keep the same people that forge and hack now from faking an ID ?
EVEN if you say the cards use non commercially available super chips, we all know that hardware can be emulated via software. For you posters who don't believe that likely, look up what an EMULATOR is.
