So yesterday (this really happened) my dad was out with my mom and two of my sisters. He was driving around by some stores for Christmas shopping when he saw something strange on the sidewalk. There was a lady on her phone. a guy on the ground next to her, and there was a guy on top of the guy...with a gun on his head. He circled back around, careful to not get to close, and yes, that is what he saw. A cop showed up soon, and the guy pinned down was arrested. The guy on top was a good guy. What would you do in that situation?
