Here are a few examples, HeinBallz.
When Mario Little walked in on his girlfriend having sexual relations with another man, he threw her face through the sink. That was horrible and could have killed her, but had he been carrying a concealed firearm, he very well could have pulled it out and shot both her and the dude.
If George Zimmerman is not carrying a concealed firearm, both he and Trayvon Martin are still alive.
If any of Trim's chokeout victims are carrying a concealed weapon, Trim is probably no longer with us.
