[What does TSA do now (in the last 6 months) that they haven't been doing to every American in the last 16 years]
Just conveniently ignore the word "you" whenever it suits you, huh?  Or wait, I guess you would read that as whenever it suits "every American" rather than you personally.  That bit about "to you" doesn't actually mean "to you."
Yeah, no.  I might have gone along with something like "I wrote that badly and actually mean..."  But you are trying to affirmatively remove the "to you" part and revise the question.  I cannot tell if you are naturally stupid enough to believe that is going to fly or just acting like it but regardless of your purpose it is clear you are going to revise, ignore,  amend, etc. to make the facts fit your conclusion rather than the more intellectually honest fitting the narrative to the facts.
Chalk it up to morbid curiosity but where you do even get this "six month" standard from?  Erecting a straw man argument?  Flying's been getting worse for years.
