If you read over our staff handbook, it says that anyone who has attained the rank of Admin or higher is permitted to warn off-duty and for obvious rule infractions. Seeing that he is a Senior Admin, he is permitted to warn off-duty and take sits off-duty (use his powers). If you believe the warn is false, then this should have gone in the report center, however Masterson has already provided evidence showing that it is valid.
