I CAN SAY ALL OF THOSE THINGS

How does all of this experience help you? Simple: I know the system inside and out. I know what prosecutors are looking for, how they assess a case, and what motivates them to offer the best plea bargains. If we can't strike a deal with the prosecutor, I won't waste my time - or your money - on defenses I know won't work. I will defend you aggressively and professionally.

There is a paper entitled “Police officers’ detection of breath odors from alcohol ingestion” written by Herbert Moskowitz, Marcelline Burns, and Susan Ferguson.  Marcelline Burns is the government’s “go to” gal in putting together scientific papers that favor the Standardized Field Sobriety Tests.  If you want to read the paper, click here.

The abstract to the paper says “[e]stimate of BAC [Blood Alcohol Concentration] level failed to rise above random guesses.  These results demonstrate that even under optimum laboratory conditions, breath odor detection is unreliable, which may account for the low detection rate found in roadside realistic conditions.
