When President Obama came to the defense of African-American Harvard Prof. Henry Louis Gates —

who was arrested while trying to enter his own home and said the white officer involved acted "stupidly,"

an erosion in his already tenuous white support began and never fully recovered.

Obama tried to make the most of this so-called "teachable moment," by holding a "beer summit"

with Gates and the policeman. The meeting however was ridiculed for being ineffectual

in terms of addressing implicit bias. The critique that emerged became a familiar one —

that the first black president was passing up an opportunity to truly enlighten the country on race.

Echoing the Mayor of Cambridge:

Obama's use of the phrase attracted considerable comment in the American media and blogosphere.

Gates himself echoed the same theme, stating, "I told the President that my entire career

as an educator has been devoted to racial healing and improved race relations in this country.

I am determined that this be a teaching moment."[8]

But how about “who told what for a long time” attributions? 

Where are the real “names & numbers” of players in this dumbed-down,  dirty-dance drama?
