At long last this dopey government has woken up to the fact that suicide bombers don't have to have a large security file, they are nothing more than pigeons used by the activists as carriers.
Anyone who appears only any MI5 intercept is of interest and needs to be fully checked before he flies.
Meanwhile the rest of us are subjected to searches that are nothing more than confidence tricks. It's about time someone asked the question "how many bombers have been arrested by the security screening at our airports?"
