"SIR On the first day of the commando phase of our Royal Marines training, the colour sergeant held up his much-scarred hands and said: “Gentlemen, forget for a moment the Fairbairn-Sykes fighting knife. Let me introduce you to the two most dangerous weapons you will ever carry.” We were taught 11 ways of killing or maiming an opponent with nothing but our bare hands. How can airport security deal with this obvious threat? Ewen Southby-Tailyour Ermington, Devon" Each time I have been to the USA and asked on entering “Sir, Have you ever been a member of a terrorist organisation?” I am reminded of Herr Hitler’s view on the Commando’s! As such I say nothing. When asked if I am carrying a weapon. Having taught Police Officers on how various items can be used as a weapon, the one that shocks them being a newspaper! Again I say nothing. When carrying a firearm, I have never had a problem!
