Many times the general public complains over an officer involved shooting. Saying it was "over the top." Or, "Too many rounds were fired. " Mostly by persons who were not there and by persons who have no clue what the police officers training is. Here is a classic example:
1986 FBI Miami shootout - Wikipedia, the free encyclopedia
"The incident is infamous in FBI history and is well-studied in law enforcement circles. Despite outnumbering the suspects 4 to 1, the agents found themselves pinned down by rifle fire and unable to respond effectively. Although both Matix and Platt were hit multiple times during the firefight, Platt fought on and continued to injure and kill agents. This incident led to the introduction of more powerful handguns in the FBI and many police departments around the United States."

This shooting gives rise to law enforcment to shoot and shoot a lot. Make sure your suspect is down and out of the fight. Just because they took one or two rounds, doesn't mean they aren't capable of committing great bodily harm. When you come across a suspect, who is armed, and is refusing to disarm, swift deadly force MUST be used to eliminate the threat. If not, you are putting others at risk.
