Is it a safety if B declines penalty?

Indy_Stu: It seems to me that you are hung up on the illegal forward pass being incomplete and going back to the previous spot. If an IFP is thrown from the EZ and incomplete then you have safety no matter what because even though it's a pass and it's incomplete it's still a running play as far as any penalty enforcement and the all but one. An incomplete IFP is the same as if the QB was sacked in the EZ. I think you've got that concept, right?

If an IFP is thrown from the EZ and it's complete then you have a different set of cirucmstances. What you have is a completed pass. If B intercepts an IFP (thrown from EZ), they CAN decline the safety and keep the ball. The issue is an incomplete IFP - it is a run and the end of the run is the spot where the ball was thrown. I hope I didn't beat to death something you already know. If so, I apologize.
