They are introducing body scanners and SCREENING of hand carried BEFORE immigration! This means that instead of the (booty for the screeners) er.....Prohibited items that had to be confiscated you'll be able to put the items in your checked luggage. No idea of when this is starting though. Also they have or will install body scanners - no info on whether you can opt out! Trying to post link but can't at the moment on my iPad I'll try later.
