When can an individual legally claim "self-defense" according to the CCP?

The concept of self-defense as outlined in the Code of Criminal Procedure indicates that an individual can legally claim this defense when they have a reasonable belief that the use of force is necessary to prevent imminent harm to themselves or others. This belief does not require prior knowledge of the assailant, a history of violence, or a specific location, such as being in their home. The key element is the necessity and immediacy of the perceived threat, which justifies the use of force in self-defense. This aligns with the legal principle that individuals have the right to protect themselves from imminent harm, making the assertion of self-defense valid when such circumstances arise.
