"We don't have a graffiti problem in Benicia." Really?

This morning I took a walk down my favorite pathway to the tunnel. Not surprisingly, I found some new graffiti that must have just occurred in the last couple of days. Since it had not been previously reported (that I know of), and that the police are presumably conducting regular foot patrols of the tunnel and didn't report it, it must have just occurred. I wonder, when was that last foot patrol?

I called Benicia PD to report it. A very friendly officer showed up at my door and patiently listened to my "enthusiastic" comments about what's going on up here. I asked him for the case number for this vandalism. He said there probably wouldn't be a specific case number assigned to it. He stated that it would be in the computer "incident log". I questioned how we are to measure the voracity of the problem and the efficacy of the mitigation strategies if there is no case record, as I have questioned in a previous post about reporting biases. "It's in the log."

I also stated my opinion that existing municipal code regarding graffiti should be strengthened as is being done in many cities around the Bay Area, and that some thought should be given to forming a graffiti task force. His answer surprised me. And I quote, "We don't have a graffiti problem in Benicia." Really?
