Authorities have to conduct investigations. Their voters demand that as part of a civilized society those deputized to keep the peace pursue and solve violations to the public order. Since investigators can't consult a magic ball, their investigations will necessarily involve people who are later cleared. One can attempt the ideal, knowing the ideal is not attainable and that reality is messy. It's a balance. It's not perfect. Some innocent people get caught up in the messy parts.
