Not a matter of opinion. Durham is huge in the drug trade. Apparently it's a major stop on the I-85 and I-40 and I-95 drug routes. That's why they have a gang problem all out of proportion to the size of the city.
SPECULATION ALERT! (for discussion purposes only . . .)
Let's say a (hypothetical) person owns a variety of companies, including an air transport company which flies mostly in Africa.
Where is it likely that person would chose to be domiciled?
If Durham, NC, is not the first place that comes to mind, ask why such a person might be found there.
(climate conducive to his health? conducive to his business?)
Consider also, the proximity of the CIA's major flight headquarters, in Johnston county, just south and east of Raleigh-Durham --

Book ties Johnston firm to CIA activity
"Aero Contractors, a private air charter company based in Johnston County, became the "home of CIA aviation," moving suspected terrorists to countries where they could be more harshly interrogated, according to a new book by freelance journalist Stephen Grey.

Last year, in part because of Grey's reporting for The New York Times and CBS' "60 Minutes," Aero became known as a possible supplier of CIA planes headed to places such as Syria, Egypt, Morocco and Jordan...

Grey said following the Sept. 11 attacks, at least 40 to 50 pilots flew Aero planes for CIA "renditions," although he was not sure whether Aero employed those pilots.
"I ... haven't tracked down where they all live ... but [of] those I know about, I WOULD SAY A HIGH PROPORTION LIVE IN JOHNSTON OR THE NEIGHBORING TWO OR THREE COUNTIES", Grey said in a subsequent e-mail message.
