It might help to know if they where they actually employed as security at the polling location as that could explain why one of them had a night stick.
Even if they are swinging nightsticks.
I only saw one night stick, was the other guy holding one as well?
And I don't think the comparison is equal comparing the Black Panthers to the Klan, I don't remember and lynching's done by the Black Panthers. I'm not saying there's not racists within the Black Panther organization, but I'm not sure you can claim all Black Panthers hate white people, the opposite can surly be said about the Klan though.
And really the videos 1:21 long, does anyone know how long these guys where loitering there? 10 minutes, and hour, all day?
