Security guards restrain Michael Stone, centre, one of Northern Ireland's most infamous Protestant militants, after he was seen throwing a bag into the foyer of Stormont Parliamentary Building in Belfast, and claiming it contained a bomb Friday, Nov. 24 2006. Police could not confirm whether the bag contained any explosive device. Stone also appeared to have been spray-painting the entrance to Stormont with the slogan "Sinn Fein are murderers,"but security staff stopped him before he could finish the last word.
