An Opinion --

This pattern of discrimination through unlawful security systems, metal detectors and searches for weapons started in most places approximately 30-35 years ago, about the time the anti-gun controversy had gained enough strength in the American culture to create a market niche (when a controversy, need or desire becomes strong enough it automatically creates a market niche in the American economy). It was about that time the professional frauds and charlatans came out of the "woodwork" to exploit it and, in the process, due to the nature of controversy, information and the way the human brain works, slowly caused a deterioration of certain civil rights to give an intellectual justification or rationalization for some people to violate the rights of certain groups or classes of people under certain circumstances and pretenses, particularly the pretense of security.
