I know that they have a very important job, and the safety of our passengers depends on the competency of these people. It may be monotinous, and hard to go through every bag of every person that goes through the airport but I dont know of anyone who could care less about their job. I was lucky enough to get the "full search" with a 4'' pocket knife in my bag (I forgot to take out before my flight) that they thorourghly inspected but never found. How did nothing catch that? Makes me feel real safe.
