There's a silver lining to the story of a crooked cop in Contra Costa County. Even though he accepted bribes from a private investigator seeking to sully peoples' arrest records, he at least made roads a little bit safer by pursuing drivers prone to drunk driving.
The scheme was pretty clever: the PI wanted to discredit people who might oppose his clients, so he hired actors to flirt with victims at a bar. The actor would get a few drinks in the victim, then supply a detailed description so that the on-the-take deputy could arrest them as they drove away from the bar.
It's clearly a huge breach of ethics. But on the bright side: at least those drunk drivers were stopped. Even though they were only drunk as part of the PI's scheme, their willingness to get behind the wheel after a few drinks indicates that they shouldn't have a driver's license.
In fact, a few more schemes like this might've helped decrease the regular DUI-related death and dismemberment on Bay Area roads.
And in Petaluma, a program specifically targeted to net drunk drivers caught two habitual drunks. Both had suspended licenses for past DUIs, but that didn't stop them from knocking a few back and getting behind the wheel. Both men were cited by police who, presumably, were just doing their job and not accepting bribes.
