Marc does not talk in detail about his nefarious exploits but he does run an elist from his
No Nonsense site: look for the Animal E-List button upper right of the first page.
If we get to know you well enough and that leads to trust, there are three folks involved with that list who were there with him.
No proof, but who cares? What he does and thinks about and teaches now is the point. Join the list, visit a bbq and get to know him yourself...
I've a few reviews of some of his work on my review site,
http://defendyourself101.ca, if you care to look.
