Swooping around for cheap and easy cut and paste stories for you the readers of the beer blog - in the guise of finding out more about global beer culture - I came upon reference to "the Chattanooga Beer Board." Apparently municipal governments in that state act as both licensing boards and regulatory tribunals for all matters relating to beer. The City of Athens in that good state describes their powers in this way:

The Beer Board has the power and is directed to regulate the selling, storing, distributing and manufacturing of beer within the City of Athens. Beer shall mean and include all beers, ales and other malt liquors having an alcoholic content of not more than five percent(5%) by weight pursuant to State law. It is unlawful for any person to sell, store for sale, distribute for sale or manufacture beer without first making application to and obtaining a permit from the beer board.

It does not seem to also include wine but does include "liquor by the drink" or, as described by neighbouring Knoxville, "liquor by the ounce". This report from a Jackson, Tennessee newspaper indicates an odd division of powers:

City Attorney Lewis Cobb said that if one of the establishments loses its beer permit, that doesn't necessarily mean that it will lose its liquor license because liquor is regulated by the Alcoholic Beverage Commission. Cobb said that he can't comment on whether the cited establishments will be fined or lose their licenses, but that each establishment will have a chance to explain why its license shouldn't be revoked.

So...even though licenses can be under review for serious events including acts of violence, their powers to pull the right to sell beer will mean that the patrons will just have to move on to the hard stuff. That is a little weird when you think of it.
