Barred, maybe trespassed

[Purple Rain]

Long time lurker, first time poster. I was recently barred from a large Midwest Indian casino after being backed off twice in the last three months. Both backoffs came when surveillance saw I was exploiting the Over/Under 13 side bet and told me I could no longer play it. I continued to play it pretty obviously, testing the limits of my session lengths, winnings, lack of cover, etc., and paid the price. But the terms of the barring leave room for interpretation.

I was not read the trespass act. But I was told that if I returned, I would be arrested for trespassing. Is there a difference? Will I be able to return safely? I worry that if I return, they could legally detain me until the cops come to arrest me. I want to milk this game, as it's the best in my area for my bankroll, but I've read that my rights are limited on reservations and trespasses are serious.

I can provide more details about the barring or my play if necessary.
