Also, if I am shooting..again and again my bullets have no effect.
Same here. I remember even shooting an attacker 6 times in the chest with .357 Magnum from my Colt Python and it had no effect.
I also remember shooting an attacker in my dreams with 15 rounds of 9mm, also no effect. Some would argue that this would happen in real life
Me too! It's like a group therapy session but not nearly as expensive!
