Well, considering that you can get kicked out of law school for lying on your application, that is a pretty strong incentive not to lie. Simply saying you are gay on your application, if you are not, might become uncomfortable if you wind up on a school's list of students who self-identified as gay, and you begin getting invited to LGBT group meetings, or run into a professor who happens to have been told you are openly gay and invites you to participate in some gay-oriented school activity. What are you going to do then?
My main point is that it is extremely difficult to catch someone in a lie about homosexuality.
I agree that it is highly unlikely for someone to falsely declare their homosexuality on their apps, but the possibility exists, and if schools begin attaching admissions boosts to homosexual applicants, I think false claims will rise.
Well personally, I'm just hoping I get an adcom that thinks lesbian = hot porno girl on girl action, and lets me in on that basis.
