"Equal protection under the law" is valid only as it relates to your rights after you're caught.......not as it relates to who the government chooses to investigate/snoop on. For example, the FBI and NSA don't eavesdrop on everyone equally.....They snoop on people who fit some kind of profile (are tied to a certain political group, make large bank transfers, make calls to certain countries, browse certain websites, etc.). And the TSA doesn't yank everyone out of the line for a pat-down.......They make their choice based on strange or nervous behavior. I guess perpetually nervous/furtive people could sue the TSA charging discrimination, that but I don't think that would get very far
