I agree, although likely for a different reason than you. If there is a true need (e.g., hernia test) and true consent (e.g., the grabbed is not an unwilling/coerced participant), there are cases where this is OK. The TSA grab-a-thon is not OK.

Aggressively fondling random people, simply because they want to fly is wrong. Why? TSA has failed to explain why this is even a good idea, much less necessary or critical, far less that this is cost effective. People are often surprised that this happens (they are not informed) and have no viable alternative (they are coerced), effectively making the willing participation a joke. This is personally offensive and degrading to many people. Reasons 4-1001 reserved for future ranting purposes.

This process is obviously a blatant overreach.
