A British House of Commons committee rightly concludes that some security measures may increase danger instead of decreasing it:
A report by the Commons transport select committee said queues of hundreds of passengers in cramped spaces could become a security hazard.
The committee recommended that reducing queues at security and speeding up check-in times should be a priority.
The Department for Transport (DfT) said baggage security rules introduced last August met “a very real threat”.
The regulations resulted in disruption and delays and, although the situation has improved, passengers still face longer queues and increased waiting times. - from the BBC
The Brits are looking for a compromise:
“I made it very clear that the one piece of hand luggage restriction which applies to customers departing the UK and transferring through the UK has no security justification,” said (Brititsh Airways) chief executive Willie Walsh.
Recent events in London and Glasgow have conspired to put the brakes on any change though.
