I remember hearing that and all I ever saw were leftists when I watched that movie.
I bet John Carpenter was ticked.

They filmed part of that Movie in the Parking Garage one weekend at the Bank of America Data Center where I worked.
The Building was prominent in the outdoor scenes of the homeless encampment, beige building with windows half way up.
Looked like a Bunker. It was located at the Harbor / Hollywood Freeway Interchange across from downtown L.A.
