The paper linked below was recently published by David Berstein, law faculty at George Mason. He argues that the recent incidence of mob violence and failure of local governments to provide law enforcement demonstrate the validity and need for 2A interpretation to recognize the full breadth of those rights applied to persons in public and towards the fulfillment of more than purely defensive criteria.
The section starting at pg. 10 also has a good cataloging of the scenarios that have occurred across the country in which police were either ordered to stand down or had become unavailable due to incapacity or absence. That's followed by a section identifying many verified examples of armed individuals protecting their communities during this period. I haven't seen all of that info captured in one place before.
