I've been trying to discern what and why you are asking this, brian.

I would very much like to keep Nigel Farmer and Daniel Sonnex alive for relentless research. We've got 35 and 40 years respectively to explore their psyche. My focus is much more on Daniel rather than Nigel. Although the relationship between Nigel and Daniel has me interested. My guess is that Daniel was acting out with Nigel to repair some damage in the relationship with his older brother Bernie.

This is, of course, Offender Profiling and has a long history with Scotland Yard. I'd like to think of the thousands, if not millions, of crimes that have never happened are a consequence of hundreds of years of Offender Profiling. Offender Profiling looks at the big picture. Sending to death the offenders is hardly worth the bother after the crime has been done, wouldn't you say? I'd rather use them as part of our toolbag to search for the future killers before the crime.

Brian, if I found Dano Sonnex before the New Cross slaughter and proposed that he had an extremely likely probability of killing, what would you suggest the next step to be?
