The use of a firearm is only justified under very strict conditions and legal rules. In most laws around the world—including the Philippines—this is permitted only as a last resort in situations like:Self-defense – When the life of the person using the firearm is in immediate and real danger, and there are no other options to escape or stop the threat.Example: If someone is about to kill or seriously harm you and you cannot flee, then using a firearm may be justified to protect your life.Defense of others – When another person’s life is at risk, and you use the firearm to protect them from harm.Example: Stopping an attacker who is about to stab someone.Law enforcement operations – Police or soldiers may be allowed to use firearms if someone poses a dangerous threat and refuses to surrender, especially during arrests or counter-terrorism.Important conditions for justification:The threat must be real, immediate, and serious.There must be no other means to stop the threat (like calling for help, escaping, or using non-lethal force).The force used must be proportional to the threat.Unjustified use of a firearm can lead to legal consequences like imprisonment, fines, or even the loss of license to carry. That’s why people trained to carry firearms undergo strict ethical and legal training.
