Reply #10: So, they are private spaces.

They lease space to other commercial enterprises.

If one of those enterprises decided to sell those t-shirts and display them in their shop window, could the mall tell them to remove the display?

If the movie theatre inside the mall decided to show an anti-war film with graphic imagery, could the mall tell them to stop?

Both of those things have the potential for volatility, but they are also free-enterprise, so I suppose they're acceptable?

(I'm not trying to be snarky, by the way - just wondering how these things work)
