Siggy,
I strongly suggest *you* “Get Real”.
What you describe is murder.
If you, your family and/or anyone in your care are suddenly put in fear of
*immediate* serious bodily injury or death by another person or persons,
many states have laws which permit you to use force or deadly force to
protect yourself, your family, frequently other innocent persons, and
sometimes (rarely) even property.
If and when such a threat is stopped and/or neutralized, you are not
permitted to execute your attacker.
Even if you are not arrested, indicted, or tried for a criminal offense, you are
still subject to civil suits. Even if you are 100% in the right, the criminal and
civil proceedings can cost you your reputation, your job, your home and other
property. The cost of defense can destroy a common man. The stress can
destroy relationships among your friends and (worse) even among your
family.
Please, for the *get real* safety of your family, take a proper course of
instruction in firearms safety and the *legal* use of force and deadly force.
Obey the law.
Over-reacting can leave your family financially destitute and without *any*
protection while you serve a prison sentence as the “girl friend” of Tonga the
Terrible.
Avoidance of potential violence is still the best option.
Non-violent resolutions are next best (even if you appear to be a wimp).
Force, especially deadly force, is the last, final, and worst resolution to *any*
problem.
And *that*, sir, is common sense.
