Individual employees would likely have the same level of interest that you&#x27;ve expressed, but department heads would have a lot more incentive to act (especially if there is any departmental rivalry).<p>&gt; ...many people get off with parking violations...<p>Is your point that these people would have deserved a ticket in the past or future - so whatever, or are you talking about some sort of municipal level karma balance where individuals are irrelevant?
