What does the following describe? "Resentment boiled in Massachusetts. In 1786, angry farmers forced courts in the western part of the state to close. The goal was to stop judges from legally taking away farmers' lands. The revolt grew. In January, 1787, a man led a force of about 1,200 supporters toward the federal arsenal in Springfield, MA. The farmers wanted to seize guns and ammunition. The state militia ordered the advancing farmers to halt and then fired over their heads. The farmers did not stop. The militia fired again, killing four farmers. The farmers fled and the uprising was over, but the American's concerns grew that the government could not handle unrest and prevent rebellion."
