Interference and force out

[SRW]

I'm having a difficult time seeing how allowing the run to score is penalizing the defense (or conversely, rewarding the offense) because of the INT-Out. The only way we get tougher with INT is when it's INT by someone who is already out or not in the game (ODB), then we get the runner closest to home. But even with that situation (ODB INT), we would be allowing the run to score and calling out the runner closest to home... how is that theory any different in the OP? Even after reading a very good debate on this here (well done, guys!), I'm still leaning toward a non-force situation in the OP.
