From the pictures it looks as though most of the people in the crowd have the same skin color as “the teen”. You know how that goes.
White boy had it coming. Who does he think he is? Jesse Owens?
Derbyshire rules apply.
From John Derbyshire's The Talk - Non-Black version
(9) A small cohort of blacks” (in my experience, around five percent”) is ferociously hostile to whites and will go to great lengths to inconvenience or harm us. A much larger cohort of blacks” (around half”) will go along passively if the five percent take leadership in some event. They will do this out of racial solidarity, the natural willingness of most human beings to be led, and a vague feeling that whites have it coming.
(10) Thus, while always attentive to the particular qualities of individuals, on the many occasions where you have nothing to guide you but knowledge of those mean differences, use statistical common sense:
(10a) Avoid concentrations of blacks not all known to you personally.
(10b) Stay out of heavily black neighborhoods.
