The New Kato Kaelin
Do you remember Kato Kaelin, the "friend" of OJ Simpson who supposedly witnessed "strange movements" by OJ that poked holes in his alibi? In the end, he was pretty much exposed as a publicity-seeking media whore who tried to make money off his connection to the murders of Nicole Brown Simpson and Ron Goldberg.
Now we have Joe Oliver, the self-proclaimed "close friend" of George Zimmerman, the murderer of Trayvon Martin.
