The greatest threat to people in the 20th century was their own governments. E.J.Rummel, in "Death By Government" notes that Democide accounted for nearly 180 million deaths. Criminals aren't the only ones who prefer unarmed victims.
Have a nice weekend Lando.

I often refer Lefties to Rummel, especially when they attempt moral equivalence arguments.
All should read Rummel, and have his site bookmarked.
