The Boston Massacre involved armed soldiers against colonials. They had guns and superior weaponry. The colonists had clubs. Comparatively‚ aren’t guns the more lethal? Can the blame truly be laid at America’s feet? No; it is unreasonable to fault America for the massacre. Analysis of the situation surrounding the Boston Massacre is necessary
