Security Personnel
For those of you who think it is reasonable for airports to employ security personnel originating from Middle East/Africa/Asian countries with mainly Muslim populations, on the grounds that they are all 'checked' may I bring to your attention the 'checked' US Army Psychiatrist who has just shot 13 of his own countrymen.
I am never happy about such people security checking air passengers (although I make no comment at the airport), as frankly they are a far bigger risk than the passengers they seek to check.
