This violates the equal protections clause, violates the right to privacy. And having dogs sniffing people in lines reminds me to much of the nazis, not to mention that dogs can be signaled to pull people aside by the handlers for any reason they want. We have the freedom of travel and the TSA violates everything this country stands for. The TSA should be abolished. They have no right and is unconstitutional, we should not be allowing the government to molest citizens or to take naked pictures of us. Anyone for these measures is against the very ideals we stand for as American. I prefer to travel unmolested.
