Several times the foreign embassy is described as being foreign soil and therefore beyond British justice. It is a myth that embassies are foreign soil.
When Susan Shaw was arrested in the Embassy, she was locked in a room, she try to warn with banging her shoes, she was barefoot, when someone open the door she run away, still barefoot, but when she go down the stair she was wearing her shoes, she opened the main door, she was arrested again but one of her shoes was left outside.
