A stand-your-ground law is a law that allows people to protect themselves by any means necessary when there is an imminent threat to their personal safety.
Also referred to as a "no-retreat law," the stipulation for personal protection extends beyond a person's personal property and into public spaces as well.
For those who have a concealed weapons permit, it means that they would be able to shoot another person to protect their own safety or that of their family member(s).
There has been a progression in laws in this regard over the past decades, from what used to be limited to protecting oneself or one's family on one's own personal property – and only using the amount of force necessary to remove the danger – to what stands now as a stand-your-ground law.
