Wearing hoodies and holding signs, Tulsa Central High School students rally in support of slain Florida teenager Trayvon Martin and his family. The killing of Martin by a neighborhood watch volunteer has sparked a national debate. President of the Central student council, Berthaddaeus Bailey, calls the gathering a ‘Hope in Hoodies’ rally. He says the idea is to show people stereotyping can be dangerous and end in tragedy. Bailey told the crowd there is hope in every situation, it doesn't have to end in violence.
