I think the Indianapolis drunk cop/motorcycle fatality is more relevant. That blood test was rejected because it went to a non-standard facility.
The only question I have was this is a simple accident or did the investigators made a slight botch which has kept this officer out of jail?
That actually is an way better example than I had... thanks. The beat cop, or investigator is this case, most likely did his/her job 100% correctly. Most cases are tossed out due to things beyond the officers control.
The court room is really a show room. The team that puts on the best show normally wins.
The FF was involved in a traffic collision, whether he was impaired at the time is the essence of DUI.
Just because noting has happened, yet, does not mean that something won't happen. There are a lot of moving parts in this case, and it just takes one part to go crazy to really screw up proper prosecution.
The City of SF will pay out, no doubt on that.
