Walter Williams

I recently saw an image on Facebook by the Bastiat Institute with a purported quote by Walter Williams.  I wanted to post it here but couldn't find a source for that specific quote.  The text of the image:

How does something immoral, when done privately, become moral when it is done collectively? Furthermore, does legality establish morality? Slavery was legal; Apartheid is legal; Stalinist, Nazi, and Maoist purges were legal. Clearly, the fact of legality does not justify these crimes. Legality, alone, cannot be the talisman of moral people.

The closest I could find is an article on creators.com from June 6 of this year.

In other words, does an act that's clearly immoral and illegal when done privately become moral when it is done legally and collectively? Put another way, does legality establish morality? Before you answer, keep in mind that slavery was legal; apartheid was legal; the Nazi's Nuremberg Laws were legal; and the Stalinist and Maoist purges were legal. Legality alone cannot be the guide for moral people.

Even better, a search turned up a piece called "When and Under What Circumstances Should Violent Force Be Used?" Williams makes many of the same points as in the prior article, but he also makes the same argument that I've been making against the ultimate threat of force from the government enforcing the law. I feel somewhat vindicated.
