Securely tie this POS (pardon language, but that’s what he is) to an exam table. Let the seniors have at him with walkers, canes, catheter tubing, ventilators, needles, etc. Many medical devices make good weapons. Imagine getting stabbed in the gut with a prong cane? Finally, leave him dangling for hours in a Hoyer lift.
Jail time probably won’t teach him anything, but a taste of his own medicine just might.
There’s nothing that pushes my buttons more than abuse of the elderly.
