Something like that. If someone comes into our personal space house, apartment, place of work, aura(I.e our physical space) and we cause harm to them protecting ourselves we could be spending years clearing our names. Case in point. I once made an error of trusting my security to my buzzer. Meaning I left my front door unlocked. I figured I had nothing to worry about my neighbors were nice. One day I look over and there's this thick brown skinned man standing just on the mat coming into my living room. He mumbles Something about washroom. I tell him I don't give a flying fuck what you want get the hell out of my apartment or I'm calling the cops. If he had chosen to attack or menace me and I took a knife to defend myself and my home I could be looking at criminal charges. So yeah of all the things little potato could do this is one.
