Altering an ID card is a crime. It is something that could get her tossed out. It is relatively minor...if this were her only infraction? I would not expect then to toss her out if there was no other infraction.
That is, if they caught her for the ID card, and she did not lie to them or mislead them at all? And, perhaps better had she confessed right away, I would think she has a shot at staying in.
Credibility is a huge factor in this...as a cadet, they are evaluating her as a potential Naval officer.
They will not let her be commissioned if they believe she is clearly dishonest.
So modifying an ID card to get into a bar...not good. But not as bad as if she lied about it afterwords. Or even if she misled them as to what happened...that would not be good at all.
So you ask a good question....
what should she admit to or not admit to.
It depends on what she has admitted to or led them to believe up until now
Again, if there is any indication she has misled them? It is likely too late. I would expect them to discharge
But if she has been honest up until now...then confessing may be in her best interest.
I would urge you to help her find a local attorney with whom she can speak with...someone she can relate this story to and who can help her make this very important decision,
If she has already misled them, or lied, confessing now likely will not help at all.
On the other hand, if she has not made any statements about this, and if it is clear they will see the altered ID, then confession now may be a good idea
I get your point about "potentially wiping the evidence away"...again, all the more reason for your daughter to speak with an attorney. Soon.
There is a lot riding on this...the Naval Academy will not keep her in the program if there is clear evidence she has lied to them about this...so she wants to be careful how she proceeds
Let me know if you have more questions...happy to assist if I can
