Can I leave a car parked overnight

I wouldn't. It's not in a great neighborhood.

If you park in the performing art deck on South St YES you can but at your own risk

Definitely not

Only if you don't want the car anymore

Yes

I would not

Yes, but would not advise it. It can be a questionable area after everyone is gone.

There are numerous parking decks nearby, but not at the center itself.

No
