Well, you must be a Packers fan.
99% of the time, a ball batted down will be incomplete ... yes, occasionally it will end up being caught, but the odds are strong that it will fall incomplete.
100% of the time a simultaneous catch goes to the offense. It has to be clear and incontrovertable that the ball was intercepted ... which historically has meant that no part of the offensive players hands are touching the ball.
You must be a democrat sore loser, because you seem to want to change the rules because you lost the game. Just like in politics, bad cases make bad case law. Changing the rules so the Packers would have an interception is what would have been a real travesty. The ruling on the field was correct by the standards of football since the forward pass was invented.
Just like your screen name of Rain Man your logic and reasoning are so far off the mark I doubt You could locate the space needle if it was in your front yard.
97% of those polled have agreed it was the WRONG call.
But keep arguing your point and then we'll know for sure you must be a LOONEY LIBERAL.
