unauthorised person, in relation to a place or thing, means a person who:
(a) is not authorised by the owner or person in control of the place or thing to have access to the place or thing;
So who decides what the owner or person in control of the place or thing can authorise or not authorise. Some of the people are are sensible and decent human beings but unfortunately the position seems to attract a certain type who revel in the only power they have ever had . With IQs flat out exceeding double figures the power goes straight to their head.
What happens if I rock up to an airport with a t-shirt saying:-
VOTE NO for
DUMP
&
MELANOMA
and I'm denied access because I offend his political views? Can he legally deny me access?
Airports a part of the transportation system and and shouldn't be political footballs . New restrictions that slow down operations at Airports should not be allowed unless a very good case can be mounted to show their absolute necessity. If that proof is shown then all stakeholders should be involved in working out the least disruptive way to implement the new security measures.
Blind Freddie can see that most of this stuff is introduced without any consultation with the people who have to try to make silly often pointless security work. It is quite obvious that no sensible uniform user friendly system was ever worked out for the security gate system. I shudder to think how many millions of man hours have been totally wasted on the current gate system.
