Very cute:
The reluctance of individuals to declare formally that their ability to operate has been impaired as a result of a security experience is understandable; however, it is important to include in any formal report any outcome or additional precaution arising from a security experience, if this problem is to be acknowledged and addressed.
A. In the first phrase, the CAA acknowledges that there is a serious safety issue here, and one they should have the authority to treat (right after stating that there is none, and they don't).
B. In the second phrase, the bureaucracy tells you what it wants. Does the guy sitting next to you keep coming back to the incident at security? That's a "measurable degradation of situation awareness", is it not? Carry a phthegmometer and do a BP check after passing security. Odds are, it'll be measurably higher as a result of your having to explain to those clowns what a phthegmometer is and why you're carrying one. Even if your vital signs are normal, checking them counts as an "additional precaution arising from a security experience."
