Handling documentation of another officer that was being overly aggressive

  Explain and discuss any one or some of the following: how you would handle documentation of another officer that was being overly aggressive resulting in an internal affairs investigation. How different would the documentation (and your liability) be if you stepped in and stopped it versus looking the other way? How do you think a rookie would react differently versus a seasoned officer with the same situation. How can we prepare the new officer to deal with the situation and document properly?
