I fly most every week as well, and I do not like TSA. I know it is needed but they could get some folks who are a little more educated and a lot more folks who understand English. I am not trowing them all in the same boat, but I am putting a lot of them in there.
Also to the times when you got the torch lighter with out being taken, it is just luck of the draw. I forgot and left my Ronson in my carry on bag last week and I left Boston, but when I cam back thru Cleveland on the way home they noticed it. It just depends on how well they look and how good they are.
