David Kopel in 2001 projected a dismal future for a disarmed Zimbabwe -- and likewise did these:

Death By Gun Control: The Human Cost of Victim Disarmament (book, 2001)and Innocents Betrayed (video, 2003)

Innocents Betrayed is a made-for-TV documentary that graphically shows the history and disarmament policies that made possible the largest genocides of the 20th Century.

Innocents Betrayed also shows how disarmament policies leave people powerless to resists slavery, lynching, crazed killers and knife wielding hijackers.

Innocents Betrayed derives much of its factual material from the book, Death by Gun Control: The Human Cost of Victim Disarmament.

For a general understanding of the dangers of powerful government, see R.J. Rummel's Death by Government. Rummel's work deals with democide, but does not deal with civilian disarmament.

I don't think I could confidently understand these issues without the above resources. I'm sorry that so many people are unaware of their existence.
