My question involves criminal law for the state of: New York

So let's say, theoretically of course, that as a 19 year old college student, you buy a fake ID to get into bars downtown. You go downtown with a group of 21+ friends. When you are downtown, a police officer approaches you and asks for ID, or the bar is raided and everyone is required to leave and show ID on the way out. What is your course of action? What are your rights?

Let's also say that you slip your fake ID to your 21+ friend (to remove penalty of fraud from you, seeing as they cannot be searched without having done something criminal). When carded by police, you say you showed the bouncers your real ID and present the police with it, or you got past security without ID and claim you don't have ID. Can they breathalize you? What is the penalty of underage drinking? Can you remain silent? Walk away?

I think you see where I'm going with this. If you are downtown and your bar is raided with a fake ID on your person, what are your options, what should you do, and what are you risking?

Any help is much appreciated.
