the burden of proof is on the claimant, therefore it is safer grammatically to ask for proof of right for someone to lay hands on you.

this is apophatic thinking (thinking in the negative). a right is something that is not a wrong.

a wrong is a theft of life, property, well-being, safety, chastity, or truth, when not done in self-defense but purely for the sake of committing a wrong or thru justification (fictional justice) of a wrong.
