That bank had as signed contract with that lady, and I am guessing that the signed agreement does not include any "we can force you to wear medical equipment to access our services in person" rule in her contract. This was a unilateral alteration of her contract once that governmental emergency order was lifted. And they trespassed her for it. In a reasonable and just system, she'd now be able to sue that bank for a lot of punitive damages for putting her through a police encounter based on their unilateral alterations to her written contract with them that guaranteed certain services would be available to her under reasonable circumstances.
