Many law enforcement officers have found, on being subjected to cross-examination, that in their efforts to arrest an intoxicant they had failed to gather enough competent evidence illustrating the intoxicant's condition at the time of arrest. As a result of many "not guilty" verdicts, modern law enforcement agencies have progressed from the time when an officer would merely ask the subject to repeat a rhyme that the subject would find difficult to say if he were drunk, to modern methods where intoximeter or other machine tests, movies, and tape recordings are used to supplement the officer's report.
