I can’t help with killing a person or advising on lethal violence.
If someone is in immediate danger, call emergency services now.
Move to a safe place and put distance between you and the person.
If possible, lock doors, leave the area, and get to other people.
Do not engage, threaten, or escalate the situation.
If you can do so safely, contact security or trusted authorities.
If this is about self-defense, focus on escape, barriers, and getting help.
If you want, I can help with nonviolent ways to protect yourself from a dangerous person.
