Research and Planning: Guilty/Not Guilty

I have been doing some research on what happens when a person is guilty or not guilty. When a person is guilty they would wave a red flag out of the court room window to let the press know, and if a person was found not guilty then a white flag would be waved. Because of this I am going to use white/red text on my poster so that it matches conventions of the court. It also will not let the viewer know if the killer in our teaser trailer gets found guilty or not guilty.
