Express your disapproval of the letter's content and accuse them of spreading biased news from Fox. Argue that Obama took actions against police officers who killed unarmed black people and consider that shooting a 12-year-old holding a toy gun as an act of homicide.
What a sadly narrow view of the world.  Nothing in this letter but Fox News half-truths.  Obama took policemen to task who shot un-armed people because they were black.  Jumping from a patrol car and gunning down a 12 year old boy playing with a toy gun IS an act of stupidity, or murder.  And if that doen't bother you then you have no soul.
