Actually this would likely be very effective. It's like the traffic-ticket lawyers. Even if you committed the crime, they normally severely reduce the penalty if not let you walk. Cash piles mean nothing, going to court is extremely costly. The defence lawyers would be very good at their jobs. I know here in Canada, the Carter defence (using an expert, arguing that given bodyweight and the times of, and amount of alcohol consumption, that the machine was calibrated wrong) against DUI was made inadmissible - which is currently being fought on constitutional grounds - as it was 90% effective at giving a judge reasonable doubt when a person blew under a 0.14 (legal limit is 0.08, but suspension above 0.05). Now the lawyers are experts on breathalyzers, will get a court order providing them with all maintenance on the machines so they can argue directly that the machines are calibrated wrong. They're apparently getting the success rates up above 60% now.
