State v. Hornik, Segura, et. al.Iowa City, Johnson County, Iowa. When the state of Iowa established that the Datamaster breath testing machine could be used to test subjects being investigated for OWI, it failed to establish a protocol for its proper use. Attorney J. Dean Keegan, in conjunction with the Johnson County Public Defender's Office, mounted a challenge to the use of the machine based on the lack of uniform instructions for its operation.
