This use to be a problem in Florida with drunk driving arrests. The company that makes the code for the breathalyzers wouldn&#x27;t allow their code to be reviewed by defendants. There was finally a precedent set that defendants couldn&#x27;t mount a viable defense without reviewing the code.<p>So for a while people accused of a DUI could wind up getting off, under the right circumstances, by requesting the source code then getting refused by the company.<p>The company finally allowed pieces of the code to be reviewed by the courts.
