If anyone ever even attempted to accost my 86 y/o mother, you wouldn’t even be able to identify them with DNA.
I was kind of thinking along the same lines. There will come a time when one of these vermin is going to hit the wrong grandmother. Perhaps a Latino gang member’s grandma or kin to someone who has had spent most of their life institutionalized in one of our prisons and doesn’t care if he or she goes back. Like you say...won’t find em.
I would go much more further and complete than that. My mother is 86. I have the property, the patience, the resources and the financial means to go full on “Law Abiding Citizen” on anyone who would attack her.
