you wont be taken seriously if you cant come up with a source which claims the picture is anything other than what the BBC News article purports it to be Just saying the red cannot ANY WAY be from blood is hardly a compelling argument and is clearly original research Find me a reliable source which says Image of BeitHanoun street with red water in it definitely no blood and Ill accept that the pictures provenance is in question however the BBC and AFP are clearly reliable sources and what they claim is valid for inclusion in articles The only question over whether to include them is whether they satisfy the fair use rationale that they add information to the article Im undecided on this but Id hate to see valuable content not included because some people refuse to trust a clearly reputable news source
