now let's speak with vincent karen. sir, thank you so much for joining us here on al jazeera.t was very interesting. we heard president obama speak and he called for national soul searching over what's happened. what do you take him to mean by that? >> well, barbara this is one of those points where i disagree with the president. the leadership moment here is not to call for calm, not to call for more dialogue and reflection. the leadership moment is to call for change. the reason why people are so anger in baltimore is not just because of the suspicious killing of freddie gray, it's also because the baltimore police department has a long and torrid history of brutalizing people in over a three-year period. they have paid $5.7 million to people who have been brutalized and beaten by the police department. so what we have here is had a scenario where people are calling for change, and the reason why the confrontations are happening and the reason why people are angry, and the reason why it goes from the oldest in the community to the youngest in the community they've all lived
