Innocent until proven guilty is more of a criminal trials thing. Balance of probabilities applies for libel. I'm not in the US, but suspect it is similar to the UK where reporters will use "alleged" if they're using the legal defence of "qualified privilege" - which allows them to repeat potentially libellous allegations without themselves being sued for libel. In the case of reporting on documents (especially those made public in legal filings) the documents themselves are subject to privilege, so the journalists don't need to use qualified privilege.
