Tim, I’m curious how you came to the conclusion that DUI’s generate revenue for the PD.
I'm not an attorney so some of my below terminology may not be correct but it should be pretty accurate description "in layman's terms." I do have a good buddy who is an attorney and he handles a few DWIs.
I have no idea how it works in any other state but in Missouri a DWI (still the official term I think) is a two pronged attack.
1. the actual ticket is prosecuted by the local county prosecutor.
2. then there's an "administrative action" that's handled by the state DMV (dept of motor vehicles). Your license is suspended and you don't get it back until the "administrative action" is fully satisfied.
#2 was created back in the '80s or '90s as a result of a M.A.D.D. campaign. The local prosecutors were plea bargaining too many DWIs down to lesser offenses in their opinion and it was making them M.A.D.D. So #2 was instituted.
It's my understanding that it's very difficult to get out of #2. There has to be very egregious police mishandling of the evidence or the stop, or some other very blatant anomaly to beat that rap. So you're pretty much screwed there.
#1, however, is still in the hands of the local prosecutors and it's still a relatively common practice for it to be plea bargained to a lesser offense in exchange for paying a much larger fine (bribe) than the "face value" of the ticket to the local government.
You still have "an administrative DWI" on your record but not the ticket. What good that does? I don't know, but it seems to be frequently done.
As an aside, I'm not so sure that #2 doesn't make the local prosecutors more willing to negotiate because they know that the state has the "big hammer" that you won't get out of.
Also, as you alluded to, local prosecutors also use speeding tickets to extort money. You can pay the "face value" fine and have the speeding ticket go on your record or pay 4...5...6 times the fine and get a "loud muffler" citation which, of course, is a "no point violation."
I, for some reason, can't seem to keep good mufflers on my vehicles and I'm occasionally bad about keeping my lights working!
Again, I'm no attorney but this is my understanding of the present Missouri DWI law and proceedings...fortunately I have no first hand experience to confirm this. Not sure if we have any MO attorneys here or not, if so, it'd be nice to hear their take.
