An off duty deputy was shot and killed when he was called to a friends house to ask her boyfriend to leave; he was unarmed. That one sentence tells us what is wrong with that incident. Your boyfriend is creating a problem and you want him to leave? Hang up the phone and call 911. Problem solved. The deputy was off duty, he should generally not get involved in police activity.
The deputy was involved in a domestic violence incident, they can often be very dangerous to the first responders, and since he is a friend of one of the participants only increases the danger. The deputy was unarmed. He is responding to a police call for service without a firearm. Would you do that on duty? Of course you would not. Why do it off duty? If he was not wearing a gun, he would certainly not be wearing his body armor.
Unless there is an overriding reason why you need to be involved, don’t get involved in police work off duty. You don’t have the moral authority of a uniform and badge. You don’t have the legal authority and civil protection you may enjoy on duty. You don’t have the gun, handcuffs, pepper spray, and body armor you hopefully have on duty. You don’t have the back up and communications you have on duty. This deputy was brave, but he made some mistakes. Learn from his death and give his death meaning; that’s what the SGT Says.
