You asked to see her AMCAS and then ran to SDN to ask if you should tell on her for lying.
You say YOU don't think she's cut out to be a physician despite her excellent stats. This has ABSOLUTELY NOTHING to do with the whole lying dilemma. You give the impression that you are already largely biased against this person, found a way to hurt them, and want validation that it is "ok" to do so.
It's really not your place, and quite frankly if I was AMCAS, I'd find you to be whiny.
If she gets into medical school because she lied about volunteering hours, so what? So do countless others. You're delusional if you think she's the first.
But, but, doctors are supposed to be honest, right?! Because no one on SDN ever lied. But if it's somehow related to getting into medical school--THAT is the lie that counts. LOL.
Lastly, YOU thinking she isn't cut out for it is irrelevant. An adcom gets to decide that.
There's a process in place for a reason. If she gets through the process, she's competent. If she doesn't, she's not.
