The Federal Communications Commission is not expected to take action over racist comments uttered by now-fired radio host Don Imus because of free-speech concerns, lawyers said on Thursday. The FCC is barred from trying to prevent the broadcast of any point of view. The Communications Act prohibits the agency from censoring broadcast material, in most cases, and from making any regulation that would interfere with freedom of speech. The agency received complaints after Imus referred to the Rutgers University women's college basketball team as "nappy-headed hos," on his morning radio program last week.
