Foolproof Strategies to Detect Drink Driving: The Ineffectiveness of a Police Officer Blowing into Breathalyzer

The idea of a police officer blowing into a breathalyzer themselves to give out impaired charges to innocent drivers is nothing short of comedic, especially when it comes to the technical and procedural flaws that would inevitably arise. Given the stringent measures in place to ensure the accuracy and reliability of breathalyzer tests, such an approach would almost guarantee a quick and damning exposure.

Technical Limitations and Legal Challenges

Technically, the primary breathalyzer used on the roadside, known as the sidewalk breathalyzer or initial screening unit, provides only a rough estimate of the alcohol content in a driver's breath. It does not provide a precise, legally defensible evidence for prosecution. The legal system requires a more reliable and calibrated device, such as the Law Enforcement Breath Alcohol Testing (LE linspace break) machine, which is typically found at the police station.

The Immediate Flaws in the Plan

The plan to have an impaired officer blow into the roadside breathalyzer and then arrest others for driving under the influence is fraught with issues. For starters, the officer at the roadside has no official record of being sober and may still be under the influence of alcohol, which would automatically invalidate any test results given by the roadside unit. This would be evident when the officer is brought in for booking and their breath sample is tested again using a larger, calibrated device. The test results would likely show a zero reading or a result well below the legal limit, thus discrediting the initial breathalyzer test.

Reporting and Accountability

Furthermore, an officer involved in such a scenario would face immediate reporting and accountability. The custody sergeant, who oversees the booking process, would quickly notice the discrepancy between the roadside breathalyzer reading and the station test. The officer would have to provide a detailed explanation of how the roadside unit malfunctioned or gave a spurious reading, which is a highly unlikely scenario. The officer would also have to deal with public scrutiny, administrative inquiries, and potential disciplinary action if found responsible for such a mistake.

Reliability and Calibration

The reliability and calibration of breathalyzers are critical aspects of the law enforcement process. The roadside breathalyzer, while handy for initial detections, is not as accurate as more sophisticated devices used at the police station. The station-based breathalyzers, often referred to as evidential breath testers, are calibrated regularly and provide more reliable results, often with the ability to print out the results as a form of legal evidence. The roadside unit, despite being a quick and convenient tool, is not suitable for formal legal proceedings, ensuring the spouseableness of its results.

Conclusion

In conclusion, the idea of a police officer blowing into a breathalyzer to gather evidence of impaired driving is not only unethical but also impractical and legally unviable. The technical limitations, combined with the thorough protocols and testing methods employed in law enforcement, make such a plan destined for failure. Instead, law enforcement agencies focus on reliable, proven methods to ensure the detection and prosecution of impaired drivers.
