Dont like getting into tit for tat, so glad we are agreed on the Israeli aspect. With regard to Police involvement, they need to be there for a professional overview of the security staff whatever the cost, not having PC`s checking every bag, obviously. Funnily enough when the IRA was at its height a similar Police presence was operated at airports like manchester.
Clearly security, these days, is done to a price and we all get what we are required to pay for. Best wishes
