"officer observations of your behavior and smell... [is] sufficient to convict beyond a reasonable doubt." (emphasis added)
I never said odor was sufficient in and of itself. To clear up the confusion that may exist, lemme rewrite in lawyerese ;-) :
Any of the following may be sufficient for a reasonable jury to convict beyond a reasonable doubt: (a) blood tests showing a Blood Alcohol Content above statutory limits; (b) failing a properly-administered battery of Field Sobriety Tests; or (c) officer observations of (i) behavior; and (ii) smell.
The chances of conviction drop, yes, but the evidence is nevertheless (as a matter of law) sufficient. Since the discussion was about what "beyond a reasonable doubt" means, and not about prosecutor/defense tactics, I think it's safe to say that my portrayal was not in fact how you read it. Also, while some FSTs really suck, I believe some jurisdictions have legislative findings concerning others. In such states, for example, a horizontal gaze nystagmus test, administered by an officer with a brief training course in optical observation, is admissible and - combined with other FST behavior - sufficient for conviction. Now, if I were a defense attorney I would of course try to discredit the officer -- have him act out in the well how he administered the test, point out if he holds the light too close or too far away, and so on -- but that doesn't change the fact that a properly-administered one is good evidence as a matter of law, and a jury verdict based on that and not much else is unlikely to be overturned.
Also, a minor point I'd like to address just to preempt it from becoming an issue: most jurisdictions now have different kinds of drunk-driving crimes. For example, in my state, OWI (operating while intoxicated) means you were operating with a BAC above 0.08, while DWI (driving while impaired) means you were drunk enough to have noticeably worse driving skill. For purposes of this discussion, I'm referring to the whole drunk-driving statutory regime as "DUI" -- what code number the prosecutor charges under is mostly irrelevant to the standard of proof.
Regardless of the AC's tone in the EFF article, his(/her?) position was mine, and you suggested that only a paralegal without a college education could agree with that position. Besides, even abuse shouldn't beget abuse.
