Ten cops had been in there. The officers had at their disposal a lot of acrobatics, totaling 6 purported "sobriety" assessments. The cops thereafter made a willpower as to a DUI/Drunk Driving arrest or not. 1977 - the ultimate report was ultimately revealed with suggestions to employ the present battery of the 3 exams.
