Stranger than fiction-  Frank Taaffe just told Nancy Grace he had a bombshell for her- that Trayvon Martin had grass stains on the front of his pants (knees). He was on top of GZ...  Nancy Grace went stone cold silent. She asked him to explain further and the show went to a sudden commercial.  the grass stains were common knowledge for a long time now, the evidence shows pictures of grass stained knee's on his pants taken the night of the incident.
