Why didn't the study compare these levels with being 300 feet downwind of
an LA freeway?

Because everyone drives on the freeways, whereas hardly anyone is a pilot, and
the objective is to eliminate the airport and turn over the valuable real
estate to developers.

So which was there first - Martin Rubin and the people in the community or
the airport?

It's not a matter of how is first, but of who has the best (read: most
expensive) lawyers.
