It began with what?  Shootings of unarmed black men?  Oh, I think it started before then.  I think it all started with the race baiting.  As to those "unarmed" black men, if the author is referring to Trayvon Martin and Michael Brown, then Rhina Guidos needs to do her homework.  Unarmed does not mean non-violent, and in each of these cases the shooters were vindicated by factual evidence; the kind of evidence ignored by race hustlers to foment racial division.  If you ignore the facts to do just that, then you, Ma'am, are the racist.
