Winter Fun Run

On the cold winter morning at the end of January, my family and I headed out to a 9k to celebrate my father's birthday. To get right to the point, the fun started while we were walking down the road to the start line. There were runners everywhere, mostly scrawny older men, but they were all smiling and pumped up. The adrenaline really went crazy when a small green car came speeding down the road, sending runners jumping out of the way and hitting one on the hip with his sidemirror. The bald headed man driving the car stopped and got out after a runner slapped his car.
I couldn't stop the giggles when the skinny runners gathered around the man. They stood yelling at each other, then pushing, then a couple of punches were swung. The best part was that a runner went into the man's car and stole his keys so he couldn't drive away. Five people were on their phones calling 911, and an elderly man held the maniac down. The race started before the police came, so it was just me, my mom and brother, and a couple of administrators waiting for the police. My mom had positioned me in front of my brother, and behind her. She was obviously fuming, sending messages that shouldn't be said out loud with her eyes to the man. As we watched the man sweet talking the cops and blaming it on the runners, I became angrier and angrier. How is that man, who nearly hit my family, me, and about ten other runners, talking casually to the three officers?
When we walked by the group, my mom interupted. She let the man know that he scared the shit out of her, and that he needed anger management. This sentence was repeated about ten times before one of the cops pulled us aside to get my mom's side of the situation. I believe that the cop was playing with us and trying to make us think he was on our side by trashtalking the man. It was starting to fascinate me, this cop's way of getting the "trust" and explaining why he couldn't arrest this man.
All of this fun really just made my day. But we all forgot about it after the suprise party for my mom after the run. Yet, I still think that the police officers could have arrested that small headed jerk who scared the shit out of my mom.
