Given the above, 99 times out of 100 all you have to do is produce a firearm and the bad guy leaves.
You don't have to be a special operator to successfully defend yourself with a firearm.
The one time I needed my weapon, I didn’t even have to pull it. I just put my hand on it in its holster and readied myself to draw it and the threats recognized the move and opted to leave us alone. I saw what I took to be the leader who, after sizing me up, looked over at the guy standing by my wife and he shook his head no and they walked away. They had a lookout posted in the street too. three of them and me with a little old 5 shot j frame. Real glad I didn’t have to pull it. 5 rounds isn’t enough.
Bingo.
