This is where you and I may agree to disagree. The training (as I mentioned to JMR) for DUIs has become much more stringent in my state. We put the officers through a tough class, which includes wet lab training. Aside from actual DUI detection training, the officer trainees have to submit NHTSAs SFSTs appropriatel (and accurately) to controlled drinkers and make an estimation of their BAC. We then produce the drinker's breath test results and discuss. This training along with moot court, and things "not to do" in DUI cases. Considering that the officer is normally the one to build the probable cause for arrest from the ground up, it is one of the harder arrests to make. Most arrests an officer encounters includes a witness, victim, and identifiable arrestee. Not the case with most DUIs. I will try to dig up a link to our state DUI newsletter, but convictions are on the rise because the harder training and more accurate DUI arrests are starting to make a difference, at least here. Obviously I can't speak for other states. I still disagree with JMR that DUIs nationwide are "routinely falsified." I will never believe that one.
