I'd like to amplify that. In the Gravest Extreme was published in 1980
Think that over for a few minutes.
Do you even remember 1980?
It's not just the weapons discussion that has changed since 1980. The legal climate has undergone a dramatic upheaval since then as well. In 1980, concealed carry was illegal or highly restricted throughout these United States. Castle Doctrine laws were rare to nonexistent. Most States held a legal duty to retreat. I don't have maps of Castle doctrine of Stand Your Ground ... the Concealed Carry map is instructive. I wish Mas Ayoob would update his book.
I concur with the wish for an update. I still think the book is highly useful for the mindset and psychological issues discussed, and despite the legal environment changes, the legal discussion still has merit.
