From where I saw the police patrolling it would definately seem that the worry was outside of the airport perimiter as well as inside. Perhaps this does lend credibility to the SAM speculation. I imagine that with war preparations, peacekeeping duties, the fire strike and now this our military must be severely stretched. Another reason why I think this was a genuine reaction to a perceived threat as opposse to pre war posturing. Lets not forget the continuing hard work of both the police and armed forces. Best wishes to the boys and girls in green and the boys and girls in blue
