Obama administration spends several thousand dollars helping organize anti-Zimmerman protests

What possible justification can the government give for using taxpayer dollars to help organize Al Sharpton rallies in a criminal case?  Even worse, the money is being used to push a political agenda that divides the country based on race.  From the Daily Caller:

A division of the U.S. Department of Justice (DOJ) was deployed to Sanford, Florida in 2012 to provide assistance for anti-George Zimmerman protests, including a rally headlined by activist Al Sharpton, according to newly released documents. 

The Community Relations Service (CRS), a unit of DOJ, reported expenses related to its deployment in Sanford to help manage protests between March and April 2012,according to documents obtained by the watchdog group Judicial Watch. 

CRS spent $674.14 between March 25-27 related to having been “deployed to Sanford, FL, to work marches, demonstrations, and rallies related to the shooting and death of an African-American teen by a neighborhood watch captain.” CRS spent another $1,142.84 for the same purpose between March 25-28. 

CRS spent $892.55 “to provide support for protest deployment in Florida” between March 30-April 1, and $751.60 “to provide technical assistance to the City of Sanford, event organizers, and law enforcement agencies for the march and rally on March 31.” . . .
