Some bar patrons are armed

Do you think it's a good idea to allow guns in taverns?  Click on this link to read a Sarasota Herald-Tribune article (10-14-10) about how some states are allowing concealed weapons in bars.  Most states forbid it, fearing the mix of alcohol and bullets.  But some argue that there would be less bar fights and crime if bar patrons might carry guns.  Guns have been called the "great equalizer" between the strong and the weak.  Or do you think this is a dangerous idea?
