About a year ago I visited LHR with some other magistrates. We went airside in a marked Police vehicle accompanied by two uniformed officers, and wearing passes and Hi-Vis jackets with POLICE on the back. We were taken out of the van, patted down, and electronically tested. Ladies' handbags were searched before being allowed through. . .. .Perhaps I should have turned up in a white Transit, and saved a lot of bother!
