The short answer is "Yes."
Ever notice that a police officer always sits after a traffic stop and writes his story immediately. Then in court he reads his account, but the accused driver gives his version from memory. That is the main reason why the judge almost always takes the cop's word over the driver's word. Both swore to tell the truth, but only one has a written account of what happened. Therefore, the judge chooses the written version over the memory based version.
