<human>: Give me the gist of the text in a nutshell

Help me, reddit! You're my only hope! (Not really but I fucking love Star Wars). I x-posted this here and in /r/relationship_advice for clarity.
A co-worker just messaged me on our internal messaging system:

>i need to hack a FB account of my daughter

I am a handy computer guy in our office but I did not see this question coming. Naturally, I am torn about providing methods to do this (the daughter is 17) and asked him outright:
>I guess first question is do you have a good reason? Not to be a stickler, but I have a huge thing for personal privacy. Also, have you simply asked her what was up?

He responded that he didn't have a specific reason, but that he had talked to her about online activities and apparently she did not seem very forthcoming. I want to tell him that it's not my place to even suggest to tell him how to parent his kids (as I have none and don't plan on it and wouldn't do that anyway) but it seems like a gross invasion of privacy if she didn't have a history that needed keeping tabs on. I feel like, from the excellent threads I have read in the past (which I cannot find now to reference), that this would be a gross invasion of his 17 year old daughters privacy. I want to tell him that if he finds something he doesn't like, and brings it up to her because he can't let it go, that she will be devastated and that her trust in him would be absolutely destroyed. 

The way to win would probably be to tell him that I don't know of a way to do this (which, in reality is the truth, I only know that he could get access if she left her account logged in), but I feel like I am in too deep now, that I may have led him to believe that I could do this just by asking the questions I asked.

Reddit, is there any way out of this?
<bot>: A co-worker asked how to get on his daughters FB profile because he is suspicious (of what, he does not know). What should I tell him?
