...no it was an intentionally vague question. defend myself? against what? how?...
Huh? The constitution of course gives a law abiding citizen the right to bear or own arms. It also states that that right shall not be infringed.
Defend against what? Pretty much all states have in their statutes that one can legally defend themselves using the least amount of force required to stop an assault as allowed by law.
LEAST AMOUNT OF FORCE is what a reasonable man/woman would construe as a reasonable amount of force needed for the event...Meaning it is up to a jury or a judge to decide if it isn't obvious at the time.
If someone verbally threatens you, you can not shoot them as that is excessive force in terms of a reasonable man/woman. I would not support shooting someone for that.
If someone pulls a knife, you have a duty to to escape the danger until all avenues have been exhausted. Only then could you be legally able to use deadly force. And that has caveats. If you have mace, a baseball bat, or anything less than lethal, you must deploy all non lethal options before one could be legally allowed to progress to deadly force.
That said, if your in your own home, most states consider that your "castle" (old law English for your primary home or domicile) and you have no duty to flee your castle and may defend it with any means available to you.
Its common sense really. Unless your back is against a wall or you have no other means to flee ( with the castle exception) deadly force would be an excessive reaction for a normal reasonable man/woman.
You must feel that your life is in immediate danger OR are in immediate risk of severe bodily harm, AND that all other non-lethal means of defense have been exhausted or you have no other means at your disposal other than the use of deadly force.
You can't shoot at someone for stealing your car.
You can shoot someone if your getting car jacked as your in immediate danger, but if you are also carrying mace, you better use it first.
If someone threatens you in a park with a baseball bat, and you are not in immediate reach of it, you must attempt to remove yourself from the situation. If trying to escape you become trapped and only if you fear for your personal safety and life could you have the legal option to use deadly force...And if you do, your actions will be weighed against what would reasonable men/woman would do in the same situation.
There are times when you think you are right but are judged wrong by your actions.
Defense from what? If you are in a situation where you fear for your life and can not escape ( other than the home thing) and unless you throw hand grenades, you have the constitutional and state right to defend yourself using the least amount of force needed.
A fist fight does not warrant lethal force (under normal circumstances)
Simply fearing for you life does not give the right to use deadly force unless you can back that up. Just being scared doesn't mean nothing unless you have the facts to prove you had no choice and was right in your decisions.
This is just so common sense to me. Unless you fear your going to die (and you better be able to prove your reasoning on that) you can't use lethal force.
That said, all of us USA law abiding citizens have that right. But if got forbid you are forced to exercise that right, you better be able to back it up in away that others would also come to the same choice of action.
Do we really want to live in a world where if one is being attacked, your only option is to wait for authorities to arrive? I can have a pizza delivered faster than I can get the police to show up.
The right to self defense is given in the constitution and really is a no brainier. Unless your an idiot, and the courts will put you away if you are, you have the right to self protection along with the right to life, liberty, and the pursuit of happiness.
