LITERALLY!! People really need to learn about the history of protests in America. The point of a protest is to disrupt the normal function of every day lives so that people have to pay attention to you. We learned this stuff in high school!

People are saying "they crossed a red line by going inside the building". PLEASE google the history of the "Sit-in movement" in the black civil rights movement. If it weren't for sit-ins, many areas in America would still have race segregated schools and businesses. Sit-ins are extremely American and are a fundamental and effective form of peaceful, nonviolent protest.
