It doesn't necessarily call for an arrest - either in theory or in practice.

For example, during the height of the Broken Windows implementation in New York, transit agencies had a policy of not allowing a vehicle to leave the depot with graffiti on it. It was obviously impossible to catch all vandals in the act, but by cleaning up graffiti as soon as it is found, it sends the message that not only are their acts futile, but that society has no tolerance for this type of behavior.

So to use your example, if you witness a vandal breaking a window, you may fine him, or arrest him if the behavior is particularly repeated or egregious - but in any case you make sure the window gets fixed ASAP such that the appearance of order may be maintained.
