Meanwhile , the Tricycle Theater in London regularly stages plays that spin off public events : the 1995 Srebrenica massacre as seen through the proceedings of the United Nations war crimes tribunal for the former Yugoslavia ; the British inquiry into the 1993 murder of a black teenager in London ; and the inquiry into the death of a British government weapons expert who killed himself in 2003 after unauthorized conversations he had had with the BBC before the invasion of Iraq were made public .
