Terrorism is nothing new; it is indeed a disgrace for humankind but it wasn't invented duirng Sept. 11, 2001. Before that date and while the wolrd suffered from terrorist activities, it was nevertheless easy to travel and nobody accepted the idea of tampering with private phone lines without justification, sniffing at your e-mail messages and such practices, more proper of a dictatorship that wants to control people's minds than of a democracy trying to defend itself from agression.

After that fateful date, laws and regulations began to change in the world, allegedly to provide for better security. However, the most immediate results are that the freedom of people is being eroded by many governments arount the world. Travel restrictions, beginning right at the moment in which you ask for a new passport, have don little to stop terrorist attacks but may be used at any moment as means to control citizens like in the Soviet world of a couple of decades ago.

Plus, there are that you may find useful to travel without paying too much, either to state officials, as well as merchants that usually charge you more just because they see that you are not a local.
