I just saw a dog get run over. The driver hit him with the front bumper, and then kept going. I saw the dog's neck get rolled under the rear tire, and I heard the dog scream.
I was too in shock to get the license plate, or think of anything to do except just drive home, shaking and crying. All I can think is that I just witnessed a murder, and I didn't do anything. I couldn't think of anything to do, but there should have been something. Anything.
I wonder if the murderer even realizes what he did.
