Beyonce called for a moment of silence for Trayvon Martin during a concert just hours after George Zimmerman was found not guilty by a Florida jury on Saturday. After asking the crowd to be silent a moment, she sang the chorus of “I Will Always Love You,” a song written by country music star Dolly Parton and brought to a global audience by the late Whitney Houston.
