^ That's more or less my impression of CB too, a low life drifter/grifter, no fixed abode, always on the look out for easy prey and an easy payday, hence the burglaries, the drug dealing, etc etc. Cunning rather than intelligent, reactive rather than proactive, reckless rather than strategic. I have no difficulty believing him to be guilty of the current child-related charges.
But, the BKA has evidence that clearly suggests otherwise if he turns out to be the serial and extremely brutal rapist and cold-blooded murderer they claim him to be. We'll just have to wait and see how the current charges against him pan out.
Perhaps the rapes indicate an escalation in his offending?
From little I have read, mostly following murderer cases, a psychopath like this may have poor impulse control, hence the inconsistency between carefully planned attacks, and obvious attacks where he was quickly arrested ...
