The mosque shown clearly in the background at 29:49 would not have been there in 1980.
The building in the background has an onion dome, but is not a mosque. The filming location is the Williamson County Courthouse in Georgetown, TX (not the Collin County Courthouse where the event actually happened) and the building in the background with the onion dome is the old Masonic Lodge, constructed in 1900.
