Just a thought regarding the upgrading last week to a Critical status for Terror Alerts defined as " CURRENT THREAT LEVEL: CRITICAL This means an attack is expected imminently" So if the security services knew about the attack then they presummably know the who, the what, the where and the how - so why then create the revised rules for travelling on aircraft? Unless of course they didn't know the specifics and were just speculating. The alert level has now returned to "CURRENT THREAT LEVEL: SEVERE This means that an attack is "highly likely" and indicates a continuing high level of threat to the UK. Not much difference really between one and the other. Bearing in mind that the type of device found at Luton July last year was I think liquid based - how come it takes a "known" threat to bring about the current restrictions on taking liquid on board an airplane? Why wasn't this concidered after the event last July? Not particularly taking an issue here however it will be interesting to see out of the 24 people currently being questioned how many will subsequently be tried and found guilty of the alleged offence. And if this threat was so severe and imminent how come our Prime Minister wasn't heading back from his holiday to deal with this?
