Letters and books (but only if they are softcover and come directly from a commercial vendor) can be sent to Christopher Cantwell at:
Christopher Cantwell Inmate #631424
Albemarle Charlottesville Regional Jail
160 Peregory Lane
Charlottesville, VA 22902
I just sent him this ...
Suggestions for others who might want to participate in Cantwell's re-education:
Eichmann in Jerusalem: A Report on the Banality of Evil,by Hannah Arendt
Mila 18, by Leon Uris
Darkness at Noon, by Arthur Koestler
Heather Has Two Mommies, by Leslea Newman and Laura Cornell
New Libertarian Manifesto, by Samuel Edward Konkin III
KN@PPSTER's Big Freakin' Book of Stuff, by Thomas L. Knapp
If you send him any of the above -- or for that matter anything else -- it might be nice to mention it in comments, so he doesn't get multiple copies of anything.
