William O. Douglas,
O'Callahan v. Parker — Opinion of the Court
“ In 1916, on the eve of World War I, the Articles of War were revised, 39 Stat. 650, to provide for military trial, even in peacetime, of certain specific civilian crimes committed by persons 'subject to military law' and the general article, Art. 96, was modified to provide for military trial of 'all crimes or offenses not capital.' In 1950, the Uniform Code of Military Justice extended military jurisdiction to capital crimes as well. ”
