Ok, let me ask you this hypothetical:
Two officers detain someone for some trivial matter, not even a necessarily legal matter.
To set it up, here's what is known by both officers: the suspect is unarmed, has no arrest warrants or previous contact with law enforcement, and he isn't a threat to the public or the officers, committed no crime, is clearly intimidate by police.
For someone reason, probably fear, he runs right before the officers are about to let him go on his way. Not even fast either, it's like a moderate jog. One officer begins to run after the guy, the other officer doesn't attempt to chase him and pulls his weapon and fires two shots but misses. Also, the cop shooting has confided previously that he has been having a bad day and isn't in the mood to put up with any crap from people. The first cop turns and see his partner take aim for a third shot that will surely kill the man. The only way this is going to end is for the man to be killed by the one cop, or the other cop shooting the other cop to protect the man. Now the question.
Do YOU think most officers would pull their gun and shoot another officer in this situation?
Keep in mind, I'm not asking what you know they would do, no one could know what they would do, but what YOU think they would do given the information provided.
