As a Google Street View Trusted Pro Photographer I have taken strings of panos (and connected into a virtual tour) in several shopping centers, ie in the common areas as distinct from individual shops. Today I tried the same in Australia, being careful to wait until no people were in view, but a big security guard ushered me out the door.
Now that is something I might have expected in Singapore but they were totally cool with all the panos I did in Jewel.
I would be interested to know the experiences of others in this regard, especially in USA.
