Today is the 64th anniversary of the Christiansborg Crossroads Shootings. On 28 February 1948 a British police officer fired on a demonstration by Gold Coast veterans of WWII. The initial shooting killed three men. Later violence resulted in twelve more deaths over the next five days. The British colonial government then detained without trial the six most prominent leaders of the United Gold Coast Convention including future Ghanaian president Kwame Nkrumah.
