A retired detective vet buddy is giving a Gun Lecture tonight and the wife and I will attend. Laptop research is available and the linked website
and photos make a good summary.
There are three cases in progress in Georgia: A policeman killed an unarmed naked man attacking him. A homeowner viewed a burglar on her cell phone / home security link, called the police, got home before help arrived and killed the unarmed teenager in her back yard. A man killed a car thief trying to crank the vehicle at a gas station. These are real world situations not the day dream of saving a movie theater crowd for a gunman.
The news is also full of stories about bystanders-including kids-hit by stray bullets.
Conclusion: There is a lot to think about before becoming a self-appointed Marshall.
I will write a final article for this series when I finish Basic Gun Carry Training.
