Will the left be calling for this guy's head?

Nah. He's no Scooter Libby.

For one, he's paid for his "expert" testimony:

Prosecutors called Shaibani to bolster their case that Plude drowned his wife in the toilet of their northern Wisconsin home in 1999. Plude had claimed his wife committed suicide.

Shaibani falsely told jurors that he was a clinical associate professor at Temple University. The Wisconsin Supreme Court concluded last year that was a lie and overturned Plude's conviction.
