"Hi, I just wanted to let you know that there are a couple of boys running through traffic and skateboarding on the traffic island of (___) Street. I probably wouldn't have said anything, but one of their skateboards hit my car."
(Dispatcher collects information)
"How badly is your car damaged?"
"It's actually not a big deal - it just hit my hubcap. I'm more concerned about the other cars. Also, I think I might have...accidentally run over it."
