Arrived at T4 JFK for my return VS flight to LHR three hours ahead of departure in anticipation of all the difficulties currently being debated. Apart from the usual metal detector gates there was no sign of the full-body scanners nor were there ANY pat-downs being enacted.

If scanners and pat downs are not implemented at the USA's busiest airport, on the main UK-USA transatlantic route threatened by terrorists, what justification can there possibly be for these measures to be in place in any other US airport?
