English Only?

In the Vanderbilt University Immigrant Community Assessment report we learn that a recommendation of the experts is to,  'Increase the supply of bilingual advocates - counselors, lawyers, and social workers - who can advocate on behalf of non-English clients and patients, and on behalf of those who are not fluent in English' in the Nashville community.  This brings up the issue that faced Nashville a couple of years ago with the English Only bill.  Do a little research on this measure.  What are the pros?  What are the cons?  Which way would you have voted?
