Every criminal case in Boulder County starts the same way: scrutinize the stop, scrutinize the search, scrutinize the statement. William Bacharach examines whether police had reasonable articulable suspicion for any stop, whether any search was supported by warrant or exception, whether Miranda warnings were given and honored, and whether the evidence supports the charges actually filed.
For DUI cases, that means reviewing traffic-stop video, Intoxilyzer 9000 calibration logs, NHTSA-standardized field sobriety test administration, blood-draw chain of custody, and whether DMV express-consent deadlines were met. For drug cases, it means challenging the legality of the search under the Fourth Amendment and the reliability of the lab analysis. For assault and domestic violence, it means investigating the full context of the alleged incident, not just the one-sided police narrative.
