Allowing broad surveillence and tracking under with the rationalization of "i've got nothing to hide" is foolish.
Here in the U.S., our country's government has been founded on the idea that the people control the government, not the other way around. Although no normal person wants to make crime an easier thing to get away with, giving up our personal freedoms and privacy in exchange for some real or imagined additional security is VERY dangerous. It starts us down a road that leads to somewhere we don't want to be.
