It's a big country! It may well depend which airports you're using. The only security personnel who didn't impress me too much were at JFK International Terminal (quite a few years ago now). For the rest, which I have used, (ATL, LAX, SEA, LAS, TPA, FLL and IAD to name some), it's been OK to good. Perhaps I have just acclimatised to the American way of doing things!
