Agree with the perception of security at LHR, but you should try CDG (BA terminal) I was there last Monday - one passport control check point for the entire building, pax stretching right around the circumference of the building. On getting through one x-ray machine working intermittently with an operator who looked completely dazed and confused, No semblence of any que, just a mass of frustrated pax. people were going through the security point with seemingly minimal attention being paid by the staff. It was a complete shambles - can't say it inspired me with any confidence going through Paris
