If he had time to retreat several times, why didn't he retreat back into the building and/or call for backup?
- Even if the person you shoot is convicted of a crime for assaulting you, they can file a civil suit against you. The other guy can literally sue you from his jail cell. What else has he got to do?
- "Guilty beyond a shadow of a doubt" is the standard for criminal trials. For civil trials, the plaintiff only has to prove a preponderance of evidence. In other words, the creep in jail who's suing you got the benefit of the doubt, not you.
- Forget about the myth of "shooting to wound." Shooting is shooting and reflects the use of potentially deadly force, and may result in death despite your best intentions. Shooting someone in the leg to wound them could open their femoral artery, which will cause death by blood loss in minutes.
So shoot to kill to keep them from suing you? Do all police officers have this point of view?
