Question: The lone woman on the bridge. What was she saying?
Answer: She was listing some of the things that naturally kill people in the world, such as diseases and natural disasters, and said that this was her time to kill people, because the Founding Fathers gave her the right to Purge.
Chosen answer: "They", which was the Government, targeted low income buildings and poor neighborhoods. The Purge was being used as cover in order to eliminate people on welfare/getting assistance in order to save money and to increase the standard of living for the wealthy.
