GP may read as a political rant, but I'm focusing in the first sentence; Brazil restricts a lot of privacy and, for my dismay, people seems to accept it. For example, I have to give up my name and ID number every time I board an interstate bus (yes, buses, not planes), law enforcement officers can stop you anytime and ask for your papers without justification (there is no "probable cause" here), and, beginning the next year, all cars will have to carry a RFID tag for tracking (gov justifies this as a way to "improve the traffic", but it will not happen -- also, a lot of countries with civilized roads never used them, so why we'll need?).

The worst part is that people grown used to it and do not notice how outrageous our privacy issues are.
