Airports should have security. Every country has security in their airports. Where it crosses the line are when you have the security preemptively treat you like a criminal, and violate your personhood without justification other than a blanket statement of "terrorists".
Security ! always have to = Neo-Fascism. But many people feel it does in American airports.
but wait, in your response to me you said that the line people wait on for security checks is just as big a terrorist hazard as the plane itself. How are you not contradicting yourself here? Which is it, we wait on lines for metal detectors or not ?
It could mean guards walking around, like in an apartment complex or mall. It could mean people watching CCTV.
This could all be done by the airline. They don't want bombings just as much as you or I. The only difference is they don't have an incentive to create a regulation that forces people to subject themselves to embarrassment or harassment.
Where is the TSA's incentive? Justifying their existence. In one hand, you have an anti terrorist, governmental agency, which will always try to justify itself, and on the other you have a necessary expense for the airlines mandated by their public relations and to reduce bad press/events from happening.
TSA is in precisely the same reactive mode: make people take their shoes off after some nut tries to blow up his shoes, etc.
