'How many more?': Gun control protests in Tennessee
STORY: More than a thousand people joined the protest organized by local mothers, packing the building's rotunda and forcing highway patrol troopers to clear paths in the crowd for lawmakers to walk through.
Demonstrators held aloft placards reading "Am I next?" and "When will it end?" while chanting "Six are dead. How many more?"
