Indeed. Out of context, the logs says 'Firearms talking to someone inside the farm' (or words to that effect). But the logs also state numerous times - 'no response'.
'Someone inside the farm' can be interpreted as a physical being inside the house, or simple an insider who is au fait with the house and the family, i.e. Jeremy.
The logs TRY to be as good a record as possible, but they are written on the fly and prone to error, or due to their relative brevity, missing a wider context. This is why testimony is given afterwards to elaborate on the detail, or clear up any ambiguities (accepting that sometimes, some will remain).
Actually, this part of the log is always misquoted, I used to do it myself. It actually states 'Firearms in conversation with a PERSON inside the FARM. Challenge to PERSONS inside the HOUSE, met with no response" - There is a clear distinction between person and persons, and farm and house. The raid team mentioned being in conversation with Jeremy and it's obvious that they are referring to him on the first part of the sentence. This has been manipulated over the years to try and suggest olice were talking to Sheila.
