Though I am not a big fan of Mayor Gray and his style of politics I let out a big "whem" after being a bit distressed that another (Black) mayor had been arrested, then learning that he was detained as part of a protest.
DC Mayor Gray Released After Being Detained For Protesting Cuts To DC In Federal Budget Deal
I noted about 3 years ago how certain Black Democratic elected officials have the powerful attribute of "stepping down off of the stage" and "standing among the people"....................to lead a PROTEST MARCH against a higher source of power.
In doing so they are able to motivate their "flock", who should be protesting against them - to focus their attention toward a greater threat.
The "Protest Motion" allows this local elected official in question to gain "street cred" among the Black community, proving that he is a man of the people. A man who is willing to get arrested on behalf of his people, sacrificing his personal comfort on behalf of the cause is real - they say.
Unfortunately these TRANSACTIONAL points of affirmation does little to overcome the structural problems that exist in cities like Washington DC. Problems which leave the Black community unable to enter the contest for economic resources from a leveraged position.
