Good analysis, and I agree.
I'm not particularly interested in or knowledgable about SKs, but remember reading some years ago K Ramsland's book about Dennis Rader, and the fussy, bureaucratic, horrific precision of his fantasies and prep (not always successful) seems to be part of RH also. Both seem to be living exponents of the raw, plodding banality of evil.
The anticipation phase prior to each crime seems to have been rather long and complex for RH, and these detailed practices of "assessment, evaluation and continuous improvement" are on-brand for the man and his professional self and deeply troubling. Very glad that this investigation looks set to continue.
