DUI Penalties

This  Radly Balko post is related to the end of my previous one, though it doesn't actually address my question.  He does talk about some incentives that can arise from exhorbitant penalties.  David Albo is a Legislative Delegate in Virginia whose day job is representing DUI defendants:

In fact, if you peruse the legislation Albo has sponsored or co-sponsored over the years, you'll find a number of bills that raise some pretty serious conflict of interest questions, including bills aimed at increasing the minimum jail sentences for DUI offenses (here, here,  and here), a previous bill calling for increased fines and points for traffic offenses (here), the admissability of evidence in photo enforcement cases (here).  Albo  introduced a bill last year that actually became law -- it suspends for one year the driver's license of anyone convicted of purchasing alcohol for anyone underage, intoxicated (!), or interdicted.

This is why my default position in elections is to vote against any candidate whose primary business is law or real estate, as those two fields seem to have the most opportunities for conflicts of interest.
