In the event of a riot, with people throwing things, burning buildings and cars,and so on, my reaction would be to get out of there as quickly as possible. I'd shoot anyone who looked like a threat to my life or health, or that of anyone in my party, but again that's it.
If the rioters were to attack my home, I'd consider that a threat to my life and health. I'd shoot without hesitation at anyone throwing something at my house, or who came over my property line.
Would such responses on the part of large numbers of people deter rioters? I don't know. I hope we don't have to find out. However, my attitude is, I don't want it, but I don't fear it.
Ditto.
