Nifong used what he could get at the time ~ plus one of the guys already had an incident pending in DC.
You have to understand, the audience Nifong was playing to doesn't care if all the Jews have Jewish names either, particularly if they're from New York City, or near there, or hang around with people from there, or know how to spell it.
The audience Nifong was playing to is the 50% plus of Durham County that is black, radical and largely ignorant. Their interest lay in prosecuting three rich white boys ... period. For supposed past "injustices," regardless of their guilt or innocence.
Your theorizing is always amusing, but this borders on silly, almost as silly as your categorizing the entirety of Southside Virginia as some sort of Klan stronghold.
