The alleged purpose of the DUI setups were to "dirty" up the arrested DUI targets so it could be used against them in non related divorce and other legal cases. According to the article, the deputy was in cahoots with a private investigator. The allegation is that the investigator would hire pretty women to meet up the the target and invite him out for drinks. Then it is alleged that after several drinks, the investigator would tip off the deputy with the location and vehicle type. The deputy would then sit outside the bar awaiting the target. It is alleged that the deputy received financial incentives from the investigator for these DUI arrests.
No one condones drinking and driving but as citizens in a free society, this type of for profit law enforcement can't be tolerated. It is bad enough that some police officers make more money on DUI overtime shifts which are paid for with quota based federal grants than they do from their regular pay check. When we allow the end to justify the means and the means is luring people into bars with pretty women and then "tipping off" a police officer who also has a financial stake in the outcome is just plain wrong.
