Excellent points!
I also thought the same thing as you did about “they could’ve found a better example.”
The fact that they can't find a better example should put the lie to a lot of leftist myths, as relates to race relations in this country.
The races in America are intermingling, intermarrying, and merging culturally. This is apparently happening at a rate that is making entrenched powers extremely uncomfortable.
The attempt to seize advantage from Trayvon's death clearly shows that desperation is beginning to set in among those who have financial and political stakes in perpetuating the notion that we're not coming together as a people.
