I don't make the rules, champ. I just follow them like everyone else.
Should also be noted that only possessing an ASIC was justification enough to enter other airside areas of this airport
No, it's not the justification. Your authorisation from the owner or controller of the place and having a lawful reason to be there was the justification. Possessing and displaying an ASIC is a condition of entry. Just because you have an ASIC
does not mean you have access.
