With your sole question being how common or legal it is for a police officer to lie on the stand, I assure you that it is not common and not legal. It would be a criminal act to lie on the stand, and, therefore, most people have the integrity or at least gut moral compass not to do so.
In either event, please have faith in our legal system. It usually provides the checks and balances to ensure that, even when someone lies on the stand, the right person becomes the victor. Notably, that's exactly what you say happened in your case.
