You decide to continue on patrol. "Savage" walks away between two house, carrying his handgun in his waistband. He will remain out of jail today, even though he has an active arrest warrant for possession of illegal, hollow-point ammunition.
Why did you let him go? You may have many valid reasons, but always be certain you can live with the decisions that you make in any given situation. As a police officer, you cannot avoid all potentially-dangerous encounters in the future.
