roeder-0604-muckColeen Rowley, Minnesotan and former FBI whistleblower, told Talking Points Memo on Thursday that the FBI missed an opportunity to intervene before Scott Roeder murdered Kansas physician George Tiller.

As details emerge, authorities say Roeder, who was convicted in a bombing plot in 1997, was seen attempting to vandalize Tiller’s clinic in the days leading up to his murder.

Rowley, an FBI agent in Minneapolis who documented FBI failures leading up to 9/11,  said the Roeder case “should have been jumped on much more aggressively.”

“The bombing in the background, even if it was years before, kind of ratchets it up,” said Rowley. That conviction, she said, “adds quite a bit to probable cause, and adds to the specificity of the threat.”
