Two police officers shot in Ferguson, MO

Just when many were beginning to hope that things would cool down in Ferguson MO, and the work of reform would avoid distractions, two police officers were shot there yesterday.  The U.S. Department of Justice, headed by a black Attorney General, had found  no cause to charge the officer accused of the unjustified killing of an unarmed black man. They also demanded reforms or a lawsuit would be filed.   Five top Ferguson officials resigned, including the police chief and municipal court judge. Apparently this was not enough for some.   The officers, who survived the shooting, were monitoring a demonstration at the police station.  However, it appears that the shots were fired from a greater distance than the demonstrators. No arrests yet.  Motive:  Could it be that the shooters were trying to provoke the officers into firing into the demonstrators?  If that was the motive, it  failed.
