I understand Actors's outrage. In addition to privacy laws, there are Elder Abuse laws on the books, such as:
Emotional Abuse—inflicting mental pain, anguish, or distress on an elder person through verbal or nonverbal acts, e.g. humiliating, intimidating, or threatening.
I hope there's a good District/State's Attorney where it happened, and the victim finds a good attorney for the civil matter.
