Never thought of search committees as ad hoc committees when we created the LFA bylaws. My opinion is that minorities aren't being slighted because most team leaders are white. The idea for to appoint search committee members came about for the wrong reasons. I disagree with your opinion. For example, you have been appointed to several search committees, and you are white.
White people can be objective.
There are librarians in this system who think that the same people are being appointed over and over again. We are saying that people of color bring different perspectives. Just being a person of color won't make you successful. I will challenge library faculty members to support more people of color on search committees. Many people are out of town or busy.
