Lesson learned from political news coverage. Have your propaganda ready to deploy before you go out and make a scene.

If you enter a political fight, you are eventually going to get a black eye. So make sure you have plenty of makeup to cover your bruises when the inevitable punches land.
This advice should also be heeded by anyone in the public whose policies or actions have the potential to create a public fervor.
