In many states, the digital readout of the breath results are visible to the breath operator, who is generally a police officer. This can sometimes be the arresting officer. The longer a person blows, the higher the breath alcohol numbers will go. Becaue almost every state's laws require TWO exhalations by the suspect, and the results have to be fairly close to each other (for you to have a VALID test), the offcier can watch the digital reading and MANIPULATE the second exhilation so that the two readings will correlate, and give a valid breath result.
