Interesting points Yes there is a policy issue with citing primary sources Using primary sources to prove secondary sources as incorrect does legitimately violate WP NOR However in this case it does bring up an issue of verifiability concerning the initial secondary source Fallon per WP VERIFY So this is problem of two policies conflicting to which I believe there is a solution I assume that such problems are not uncommon I ll look into it and get back to you In the meantime I d advise against edit warring The issue will be settled in due time Please note that I am not an admin and can not block people as such
