NEW CASTLE, Del. (AP) - Officials at William Penn High School are allowing a temporary change in the dress code so students can wear hoodies.

     Students will be allowed to wear hooded sweat shirts on today as a silent demonstration in response to the killing of Florida teenager Trayvon Martin. Principal Jeffrey Menzer granted a request from a student leader who asked that a school policy banning hoodies be lifted for one day so students could join a national call for justice.
