I wonder whether courts (American or Jewish) can help sort it out. Could you sue a person who is creating a risk to you and, thus limits your behavior and business? Let’s presume for simplicity: I have a store and if all customers were vaccinated, I would not need any additional measures. So, can I sue all non-vaxed people who came in for the expenses of masks, barriers, testing, air filters, etc?
There is a reason parking tickets work – a lot of small punishments are effective in preventing most of bad behaviors.
