Dear Lord. One wonders how many lives may have been or will be potentially ruined by this:
“As a matter of public safety, the Alcotest should be suspended from use until the software has been reviewed against an acceptable set of software development standards, and recoded and tested if necessary. An incorrect breath test could lead to accidents and possible loss of life, because the device might not detect a person who is under the influence, and that person would be allowed to drive. The possibility also exists that a person not under the influence could be wrongly accused and/or convicted.”
