A snub for Abraham?

Lynne Abraham has been a popular but controversial D.A. Her challenger, Seth Williams, has been thought to have slim chances. However, his recent endorsement by the police association has caught some attention -- is this just backroom political stuff (or payback for slow handling of internal investigations), or are they really impressed with his new ideas about community-based organization of the prosecutor's office? I'm less intrigued with the process issues here than with the fact that this is one of the few really job-based (as opposed to political) endorsements out there for this post. I'd think that the opinion of the feet on the street should carry a lot of weight in a choice of prosecutor.
