Ok, so the cop gets a report of a break-in, so he responds. Unbeknownst to him, it is the resident of the house trying to get in. He knows nothing about who lives in the house.
He responds because he was close, and the dude refuses to come out because he's a black guy and the cop is white, so its automatically profiling.
The cop is about to leave, but the professor continues to heckle him until the cop arrests him, in view of onlookers and other cops (including black cops).
The professor paints the cop as a racist. Funny that the man is a professor in African American studies. Agenda anyone?
Obama calls him stupid.
Turns out that cop is a teacher in his police department who teaches other cops how not to profile.
Long story short, the only ones who acted stupidly were Barack and the professor.
