What guarantees that the 12 are all good men and true? Besides Raggy Military Justice does not require those 12 men, it requires whatever is required to make up a Court Martial panel. Tell me whether or not martial law had been declared on the 25th April 1916? The other thing you seem to have overlooked, those who rose in Dublin did so as armed men in uniform, called themselves the Army of the newly declared Republic and read a Proclamation that stated they were allied to Germany - on what grounds should any of these men been tried as civilians in a civilian criminal court? If you opt for violent solutions then accept violent consequences.
