Who’s a Rat – database of those who do and tell Posted on November 16, 2006 by Tamara Thompson December 1 UPDATE: This site was just shut down, possibly because of the heat on the Web site owner due to his own legal troubles. The last cached version from The Wayback Machine is April 24, 2006. Who’s A Rat is an online searchable database of criminal “informants and agents”. The site also has a message board where participants post requests for information on individuals. A federal judge cited this database, proposing that “judges consider sealing documents or hearing transcripts” to prevent the release of names of informants. Read the posting at Grits For Breakfast.
