You are assuming that MR reads that page, and also that MR believes them over LE. What reason would he have to believe them over LE? And also what if he saw it and called LE and "asked" about it and LE told him something different. Again, LE could have told ER one thing and MR another.
A question for anybody that believes MR was oblivious to the fact the child spotted by the postman was not Dylan
Why on earth would MR not be on at LE to do more to spread the word that Dylan was infact seen on Monday afternoon as after all this would of been the only break in the case so far?
It makes no sense for LE not to have done more if Dylan had been seen that afternoon as it changed things and so did MR never wonder why LE was not out in the media asking people to think back to Monday afternoon and to anymore possible witnesses ?
