Man fingers son-in-law as terrorist, surprised FBI believed him

Man angry with son-in-law fingers him as terrorist to FBI: "STOCKHOLM (AFP) - A man in Sweden who was angry with his daughter's husband has been charged with libel for telling the FBI that the son-in-law had links to al-Qaeda, Swedish media reported on Friday.

The man, who admitted sending the email, said he did not think the US authorities would stupid enough to believe him."

I think we can all identify his first mistake.
