If you own a firearm, whether you carry regularly or not, this Is Why You Need Concealed Carry Training. The class is not just about firearms and how to carry concealed. The most important aspect of the class may be the laws regarding the use of deadly force. Even if all you do is have the firearm in your home for self defense, you can't just fire your gun at someone any time. There are specific circumstances when it is legally justified. Other than that, you are going to jail. The man in Minnesota fired at a car as it was leaving his property. The man thought the people in the car were "casing" his house. That is NOT legal justification for using deadly force; Not in Minnesota; Not in North Carolina.
