No. I am operating in the
knowledge of how things actually work, having been a senior investigating officer for five fucking years.
The fact that someone has a DNA sample on file is absolutely fucking meaningless to an investigating officer. ALL it means is that someone has been arrested for a recordable offence of some sort. It is of no investigative value whatsoever.
You are talking bollocks. Go and find your "interviews" and they will either turn out to be talking about something else (like, perhaps, a
conviction for a particular type of offence) which
does have some investigative value or I will tear them to pieces as well.
