Because of 2004 state legislation, tens of millions of dollars in drunk-driving and criminal-traffic fines go to counties now instead of cities. This led Bill Jonson to say to a reporter, "In theory, we are going to still enforce DUI laws, but it does send a message that maybe it's not as important."
So the city is motivated by the cash, not the consequences? Drunk drivers are a danger to themselves and others. Seems like a good reason to stay vigilant. And not just in theory.
