What's wrong with this sign?

Take a look at the photo and tell me what's missing. Every time I see a sign such as this one, it bugs me because it is missing punctuation, or some sort of distinction between the Trespassing and the Violators.

Imagine this dialog:

Me: Hello, City of (fill in your city here)?

City: Yes, how can I help you?

Me: I have a question about signs I find around the city.

City: Which ones?

Me: The ones that say, "No trespassing, violators will be prosecuted."

City: What is your question?

Me: Well, it seems there should be something between Trespassing and Violators to show they are separate sentences.

City: No, they're right.

Me: They're right?

City: Yes, it is intentional that they are like that.

Me: Can you explain?

City: Yes, it is quite simple. There is no money in the city budget to prosecute trespassing violators.

So according to the City, the number of trespassing violators that they will prosecute is zero.
