Vice president Joe Biden met for nearly three hours with representatives of the film and television industries Thursday night to discuss ways to shield children from depictions of gun violence, but it was unclear whether the meeting accomplished anything other than a photo-op for the two industries to reiterate their past position -- that they already provide the tools for parents to control their children's viewing choices such as the MPAA ratings system and television's V-chip. (Biden is due to meet today (Friday) with representatives of the videogame industry.) But while the entertainment reps said in their statement that they look forward to doing our part to seek meaningful solutions to the issue of gun violence, pro-gun advocates that Biden met with earlier in the day appeared to dig in their heels at any further regulations. In a statement released after the meeting with Biden, the National Rifle Association said that Biden and his task force spent most of the time on proposed restrictions on lawful firearms owners -- honest, taxpaying, hardworking Americans.
