Fascinating story, thanks for sharing it! And good for you for intervening and quite possibly saving the lady’s life.

I am sorry to hear about your neighbors’ uninvolved behavior.

Reminds me of the Kitty Genovese story. Although I understand that there are now arguments that reports about the neighbors were badly mis-stated.

I have been fortunate to not have had to shoot anyone. Or even had to seriously consider it. I have been in fist fights. But mostly in Pittsburgh back in the days when there were generally understood rules about the limits.

Edit - Cut and paste missed the first line, had to add it.
