As proposed on many threads on THR, one of the best sources to learn about the legal implications of a self defense shooting is Andrew Branca and his
Law of Self Defense book and course. He has addressed all of the aspects found in this thread.
The most economical route is to the advantage of his
free book offer [
edit adds, you do have to pay for shipping] currently (Jan 2022) on his site. Or, you can pay $25 for it on Amazon. Of course, you have to actually study the book, not just leave it on your
rountuit table.
More accessible, but more expensive, is his video course, which is quite good. Just be sure to buy both his full course and his shorter state-specific course for your state(s).
Tip: the slides from his state-specific courses are available for $10 each from Amazon as Kindle books.
Better tip: the book includes the state-specific details for all states in an appendix.
Note that Massad Ayoob also teaches these issues from a different perspective, and in his book
Deadly Force: Understanding Your Right to Self Defense he tells readers to also read Branca's book. In
Law of Self Defense Branca tells folks to read Ayoob's book, and credits an Ayoob class for prompting him to write his book.
