First let me state that I am a retired law enforcement officer. Shooting at paper targets and shooting at a human being are very different. The human usually shoots back and usually shoots first if given the chance. Knowing that fine line of when to shoot and when not to shoot is the key point. The seconds it takes for you to make a decision to shoot is nothing compared to the hours and days the attorneys have to try to prove you wrong. I have, and I carry firearms most of the time. I respect those who choose to carry firearms but please, please know when you can and when you cannot use deadly force. Some states have classes on this subject and if your state or county has these classes I urge you to take them.
