The Boston Massacre was a result of the colonists "antagonizing" the British. The Colonists were telling the British that they didn't need them and that they should get out of the country. They were also throwing stones at the British and yelling "shoot, shoot at us!" The British thought that the colonists were rebelling, so they decided to open fire, killing 5 "innocent" victims.
