Whichever way this is viewed, and as far as I'm concerned no description of " a fair/grey haired person/body was mentioned, even if the light wasn't particularly good a fair/grey haired body would still be distinguishable. Two bodies has been described as having been seen and if that was recorded sobeit.
You can't mix up two bodies if you suddenly decided that it was a male with shoulder length hair, mistaken for a woman.Where does body number two come in ? One male mistaken for two people ??
When a person lays dead, an officer will describe every detail, including hair colour. The size/ build of Nevill should have given the officers a clue of the gender ?
Nobody said it was mentioned, the point was a silvery, long haired male COULD appear as a female when they are face down, bent over, head in a bucket.
This is not a situation where a police office has all the time in the world to take the inside leg measurements of a body... it is a police officer poking his head above the parapet to try and see anybody inside a kitchen (at the risk of being shot should a shooter be in the kitchen!).
Imagine the following communications over a radio...
'One female dead in kitchen'
Second look...
'One male dead in kitchen'
Then HQIR who are listening in, interpret this as two dead in the kitchen. The logs we read are the intepretations of a remote listener, and relayed on to yet another party who will repeat the same, thus you get two logs with the same error, all because of the uncertainty on the ground.
Once inside the building, radio comms from inside the building would likely be nil unless there was an emergency - remember. at this point, the police could still be facing someone with a gun so a) need to focus on the task in hand and b) do not want to relay any information to the potential threat.
But let us suppose for a moment that there really were two dead bodies in the kitchen...
What possible motivation have a Firearms Unit got to move a dead female up a flight of stairs into a bedroom and pose her as a suicide victim?
Which is the more plausible to you?
