And just for the record I am in no way condoning the actions of security who allowed him to go through.
I think you are, inadvertantly or subconsiously. Pretty clear to me that security did not simply "allow" him to go through, they instructed him to do so.
A lot of us on here will
not take BS from security staff, but that's because we're familiar with the process. I imagine the overwhelming majority of the general public will trust (for want of a better word) that those in security have both the knowledge and authority necessary to do their jobs. Or be cowed into accepting a procedure even though it doesn't feel right to them. And if one is 79, then...
Give him a break; place the blame where it belongs
