The camera man is right. It is likely to be a private owned mall. If there certain reasons to close that door then they have the right to. It is not a public right of way. Neither are they obliged to tell you why it is closed.

That weekend ended up having cop cars burned down and 100’s or maybe 1000’a if people arrested.
