Fortunately, one type of police officer death that is relatively infrequent is an accidental shooting of one officer by another. Since 1981, according to the report below, there have been only 26 such deaths.. The report below is, to my knowledge, the first and only attempt to deal with this topic in a fairly comprehensive fashion. With proper policies and training, most of these incidents should be preventable. Does the police agency in your jurisdiction have such policies and training?
