Then if you are not rich you cannot even call the police because you cannot afford it. It's better to abolish police and not jail people for self-defense.
In that case, would your only recourse be to hire a private investigator to identify the culprit, and then personally show up at their house to exact your revenge? That doesn’t seem sustainable.
We now a standoff between your private army and someone else's. Seems like an extraordinary inefficient way to achieve justice. (And, one that will likely end up being quite deadly for all parties involved.)
