Several states now allow constitutional carry, which simply means you can carry a gun without a permit. As the name implies, states that allow constitutional carry believe that the 2ndAmendment to the U.S. Constitution is a citizen’s concealed carry permit.
As you can imagine, this idea has caused some consternation among the anti-gunners, who claim that, without a permit, there is no control over guns. Not only does this show that gun control is more about control than it is about guns, it shows that anti-gunners think a permit somehow automatically makes a person responsible. It does not.
Your requirement to be responsible with a firearm is not linked to a permit or even to required training. Your requirement to be responsible is neverending. You will be held accountable for your actions regardless of whether or not your state requires that you have a permit.
Whether or not your state requires training, you should seek out training well beyond the minimum. Such training will help with your decision-making. Your life depends on it.
