He has more than two, but he has shown me only the two you are speaking about, namely (1) which I first saw in ES `s office, and (2) the one of Sheila on bed with only one entry wound to the neck...
If there are more than two alleged photgraphs then the placing of these photographs in the public domain, in my opinion, would definately prove a cover up / conspiracy. It would not be possible to pass off more than 2 photographs under the guise of an administrative error or confusion.
NGB has indicated there would be nothing to fear in releasing these photographs into Simon McKay's office / public domain. So, in my opinion, just release the alleged photographs and get the hard worked for result for Jeremy.
