“will the anthrax attacks forever remain in the same temple of mysteries as the JFK assassination?”

There is no mystery. Lee Harvey Oswald, acting alone, did it because he was a Marxist who hated America, and because he was a nutball loser who wanted to make a name for himself.

Gerald Posner in “Case Closed”, among others, has exhaustively proven this true, and demolished various conspiracists’ claims.

The media, left-leaning even then, was eager to blame it on Dallas segregationists or other right-wingers, and was disappointed to learn otherwise. Ever since it has fostered an artifical confusion and “mystery” about a relatively straightforward event.
