Current uploader verbiage says:
This is my own work - I confirm that I am uploading this file following the terms of service and licensing policies on Gun Sense Rebuttals.
This statement says the upload must conform to MY WIKI policies-- NOT WikiMedia.org policies, or Wikipedia.org policies.
My wiki policy is that public domain and other legally-shareable documents are allowed.
So the statement "This is my own work" is incorrect, as it is too limiting.
