Lantley, I have had a couple of times where having situational awareness has kept me out of trouble. By being aware of what was happening around me, I have stopped people from getting robbed at a mall. I have reported burglaries in progress, and stayed around to assist officers take people into custody. I assisted a police officer that was outnumbered by the bad guys, by the way, this is a normal situation for a police officer.
Almost every active duty or retired officer has done this. You are never really off duty or totally retire. You are just out of uniform.
My wife has been with me for over 35 years. If I "go on alert" she looks for escape routes. She will be the woman helping to get people to safety in the event things go to ****. She would not be the useless person sitting there crying and waiting for someone to rescue her. If needed , she can and will grab a firearm to protect herself and others.
This is life for all people in the armed services, police officers, firefighters, and first responders of all kinds. We are not being paranoid, we are being realistic. **** happens.
