Some stories are covered because they have to. There was no way that CNN could avoid not covering this story, considering that it was there during Senate hearings on Cuba last week. There, longtime Cuban dissident and activist Jorge Luis García Pérez spoke about the problems in Cuba and President Obama's Cuban policy. As García Pérez said, "Policies of appeasement only strengthen the repressive apparatus and the impunity of the aggressors."
Here is the video posted by the YouTube channel of Senator Bob Menéndez (D-NJ) that ran on CNN. According to García Pérez's wife, CNN reported that García Pérez was arrested the next day by Cuban authorities, detained, and pepper sprayed. He is still in custody.
