I was referring more to simply entering the sterile area, not boarding a flight, but does it really matter? The whole point of the sterile area is that it is well, sterile. Once an LEO is past security then a weapon could be transferred to a passenger, unless the TSA is relying on those ultra super secret gate checks. I personally do not care of an LEO is allowed in the sterile area, as I'm not a paranoid worker of a certain hyper-paranoid government organization. I was merely pointing out yet another whole in the joke of security that the TSA provides.
