Below is the link to the US Supreme Court’s record of the US vs Abel. The whole document is quite a daunting read but if you skip to page 362 US 242 you will begin with Justice Douglas’ dissenting statement (dissenting from the verdict) followed by Justice Brennan’s and Justice Black’s and they are well worth a read.
