In S02E08, Doakes breaks into Dexter's apartment and finds Dexter's blood slide trophies.
In S02E09, Doakes goes to Haiti to ask his old fixer Leones to get the blood slides analyzed in a hospital in the Dominican Republic. Why does Doakes do this?
What useful and usable information could Doakes possibly get with such an analysis that he couldn't get anywhere in the US?
Why doesn't Doakes just go to any US authorities (e.g. his own department or the FBI) with the blood slides (rather than risk losing the slides or, as it turns out very conveniently for Dexter and the plot, risk getting the slides found in his possession and being framed as the Bay Harbor Butcher)?
Yes, at this time Doakes is already on administrative leave (after being baited by Dexter into beating up Dexter in the middle of the Miami Metro office in S02E07). But if Doakes were to simply honestly admit to any US authorities that he had broken into Dexter's apartment and found the blood slides, wouldn't he be guaranteed of far better results than trying to discreetly get the slides analyzed in the Dominican Republic?
(Again, an answer should address what superior useful and usable information could result from an analysis of the blood slides in the Dominican Republic. With the blood slides Doakes found, Doakes already knows that Dexter is a serial killer. So, what Doakes seems to want is more definitive evidence and leads that could be used to eventually convict Dexter in a court of law.)
