The TSA is a show. All the lines, the screenings, the taking off of shoes and belts, the snarky indifferent attitudes, the government sanctioned groping, is all nonsense. But there is now a TSA lobby which has entrenched itself and we’ll likely have to deal with it forever.
And don’t forget the radiation doses.
Of course, alternatively, you can just “fly private” and stroll across the tarmac to your plane from your car. No TSA for those with private planes. Wonder why that is?
