It doesn't just happen to pilots.
One of the sad consequences of 9/11 is the regular occurence of incidents where 'security ' personel ( right down to shop assitants,) use their new found power to resolve personality clashes by invoking 'procedure.'
If this continues the result will be a PC (and boring) population cowed into frustrated silence but with frequent outbursts of violence toward, often innocent, security employees. Inevitably it will be the victims who will be prosecuted, not the bullies. Nothing changes.
In similar vein discussing, or even joking about, fire in a crowded theatre is not the same as standing up and shouting "FIRE" but our newly promoted arbiters of 'safety' do not seem to appreciate the difference, hence the sight of pensioners being hustled and manhandled from boarding lounges for "inappropriate' remarks.
