Burden of proof, in resting with the claimant, must move with the claimant as well. If I say something and you tell me you disagree, I still have the burden of proof, beause simply disagreeing makes no claim. But if I say something and you tell me I'm wrong, the burden of proof is then upon both of us, proportioned between us according to the status quo. amirite?
yes ...only use your mouth for known-fact or be forced to prove it
I disagree..
