A Tennessee defense attorney is arguing for a change of venue in a racially charged double murder by citing postings on Internet blogs along with newspaper and television reporting — a move that legal observers say may become more common.

Attorney Philip Lomonaco of Knoxville, Tenn., called the Internet “the largest unregulated source for information” in the community, and said it had been used to “outrage and taint any jury pool” that could be seated to hear the case against Eric Dewayne Boyd.
