You're confused. The onus isn't on those expressing skepticism to source it, but on those who find it credible and think it's reasonable to publish and disseminate it. The whole purpose of this website is to challenge the lies of the corporate media which is constantly publishing unsourced claims from anonymous officials or other media sources which uncritically publish these. Classic technique to manufacture consent. What's "pathetic" is a media analysis site practicing the same journalistic malfeasance.
