Police Won't Rule Out 'South Park' Link in Times Square Bomb Attempt

Authorities have not ruled out a link between Saturday's failed Times Square bombing and a New York Islamic group that warned the creators of "South Park" that they face retaliation for lampooning the Prophet Muhammad.

New York Police Commissioner Raymond Kelly told reporters Sunday that while no connection has been established, detectives are looking into whether the botched car bombing may be linked to a warning issued last month by Revolution Muslim -- a radical Islamic group based in Queens -- following last month's 200th episode of Trey Parker and Matt Stone's "South Park," which included a caricature of the Prophet Muhammad disguised in a bear suit.

I know this is Fox News, but here is the link.

I seriously doubt this actually has anything to do with South Park. But I still find it interesting they haven't ruled it out yet.

If I were trying to make a statement, I would go straight to the source. Not a random area near where the company that owns the company is located.
So why hasn't it been ruled out yet?
