Fox news has since stepped it up but as of just a few days ago, they had little interest in the Trayvon Martin tragedy. As noted by Think Progress, all of the major news outlets covered the Trayvon Martin story except Fox News.
Geraldo Rivera, however, stepped up in his usual fine form by suggesting that Martin was to blame because he wore a hoodie.
… I believe that George Zimmerman, the overzealous neighborhood watch captain should be investigated to the fullest extent of the law and if he is criminally liable, he should be prosecuted. But I am urging the parents of black and Latino youngsters particularly to not let their children go out wearing hoodies. I think the hoodie is as much responsible for Trayvon Martin’s death as George Zimmerman was.

I know that I always assume anyone wearing a hoodie must be packin.
