Jack still believes that something can be proven true or false by the source, not by the actual information presented.

Why? SO that if it disagrees with his beliefs he can say it is untrue. However if it agrees with him, he can claim it is true.

It is hard to loose when you got that going for ya.

Likewise when one can blame everything on someone else, life is real easy. Just sit back, complain and point fingers. Ain't my fault.

And the accusations are easy to prove with the "source" method of verification.
