Just never talk to cops unless you are being detained and only do so once your lawyer is there. There is no benefit to telling them anything. They are there to catch you so the court can process you. They have ZERO impact on your sentencing unless they decide not to charge you.
They lie all the time to get you to confess...It's not illegal for them to do that.
If you get caught like that in a club again, just leave...They aren't allowed to detain you even if you have committed a crime unless they place you under "citizens arrest"...Which these days, any good lawyer can get a case thrown out for.
