The way Nifong works, they probably found a hair that matched one of the LAX players, and he brought the AV in and showed her a picture of him and asked her if it was one of her attackers. 100% positive ID.
I heard on the hourly local Radio news (680- WPTF) that the report also criticizes Duke for not having more input from NON-WHITE MEN on the actions to take in the days after the attack.
Seems the committee feels NON-WHITE MEN would've done the 'right thing' and proceeded with Punishment absent charges.
