Yep! You recognized it for what it is. In the field of disability services, we refer to such a witch hunt as "informing your own bias." It is nothing more or less than a way to justifying your right to treat and consider the student differently... and it doesn't fly! I am always more than happy to share information with faculty who want to know how they can help, while I am less than forthcoming with faculty who only want to confirm their suspicions.
