Execution by firing squad would also be acceptable for the insurrectionist trash, Jjit-taek-dong

While dragging him to Gwanghwamun Square for decapitation followed by posthumous execution (bugwan-chamsi) is the top priority, I don't think execution by firing squad is a bad choice either. However, posthumous execution must be carried out. Whether by decapitation or firing squad, the leader of the insurrection, Jjit-taek-dong, must be executed.
