DS Jones didn't like JB from the outset. It goes to show how times have changed can you imagine in 2025 an officer saying to a bereaved relative ( which at that point in time is exactly what he was deemed to be) " you must pull yourself together "
How do you know what appeared to be a dislike for JB from the off was not just part of his persona? Maybe he would have been similar with just about anyone?
Maybe he had mental health issues?
Maybe he had addictions? Hence his frequent drinking on the job. First at JB's on 7th Aug and then with PE when he collected the silencer on 12th Aug. These are just two occasions we know about within the first 6 days.
Maybe he was a closet gay and JB stirred something in him hence the comment 'If I'm hard its for a reason'.
I believe he fabricated the outside of the silencer and secured JM's testimony. If I'm right then given he was an officer for some 24 years prior to WHF I bet he got up to all sorts. I get the feeling there's a bit of a back story here.
