Cause you might be an illegal, or al-queda, or worse. It's the whole locking down of the country thing after 9/11, our rights got trampled on so badly after that occurred it was crazy. Granted, we were slowly losing them prior to that, but after 9/11 we flew our flags and talked crap about how much they hated us for our rights, and then we turned around a few months later and gave them all away. It's why the border is so screwed up, it used to be they were looking for illegals and drugs, now they are looking for anything JUST BECAUSE THEY CAN. It used to be I could drive to Disneyland on I-10 only stopping for potty breaks. Now I have to stop 3 times between Phoenix and LA for random armed thug visual searches of my vehicle. (FUCK YOU BORDER PATROL!) It used to be you could get on a plane and had to have your baggage checked and walk through a metal detector, now they want to virtually strip search you and/or grope you in addition to the rest.
Not going to blame it on either party because they've both had a hand in implementing crap that have stripped us of our rights, but I will say that I'm extremely disappointed that the current administration hasn't done a single thing to roll back some of the draconian measures implemented under the previous admin. It sucks knowing my only power is that of a vote that really stands for nothing aside for which sell out and corporate shill to stand behind.
