With the one-year anniversary of 17-year-old Carlos Sousa Jr.'s death by tiger approaching -- if you recall, it happened in Christmas day of 2007 -- the two brothers who survived the big-cat attack have filed a federal lawsuit against the city and county of San Francisco, the SFPD, the zoo, and a public relations firm hired by the SF Zoo just after the attack. The Dhaliwals claim that the "tiger enclosure was lower than recommended national standards" and that "the zoo started a smear campaign against the Dhaliwal brothers following the attacks." (KCBS)
