Actually, Mat, I believe it should be made clear that as there was NO RESPONSE, the police were neither "in conversation with" nor in dialogue with as BOTH have a requirement of two or more persons.
Yeah, that's my point. Maybe I made it poorly, the police say they attempted to contact someone/anyone inside the Farmhouse.....they say they got no response. But people ignore the "no response" and claim that because they attempted it means they were successful, I could attempt to win the Lotto tonight - doesn't mean I will!

"No response" is clear......NO RESPONSE!!

People forget that the logs were written by someone in the control room, they weren't at the scene, they were simply trying to make sense of what was being relayed to them from the CS. Now people are trying to make the inevitable errors into a conspiracy.
Clear errors, yeah. But this is one that dies on its arse right away because the fact there is NO RESPONSE was recorded as NO RESPONSE.
So it seems there are errors even where there aren't any.
