It is unimportant whether she had any prior involvement in editing the page as that is not of the key points of the criticisms made. I have read the BLP policy and "Delete first, discuss afterwards" does not seem to be an adequate summary of it. Summary deletion is sanctioned with regard to certain kinds of violation or concern, not generally. None of the concerns cited as justifying summary deletion were applicable in the case of the Alex Jones material since all of the claims made were backed up by a reliable source.
