Just an idea here now, but ....
If the NRA hot shot lawyers were to PRO BONO go after the entertainment industry for their gratuitous movie and game violence as making kids violent (think of all the smoking studies that say a teen watching a movie with smoking in it create 48% of those viewing start smoking).
Sue those lib bastards that are teaching our youth to kill because it's a game.
All they have to do is pick the venue carefully and win one. Once they have one, they can then go to every victim of EVERY ACT OF VIOLENCE where the perp was influenced by movies or games and represent them in court to sue and sue and sue the bastards. Make them pay damage awards and you'll see them sing a different tune.
NRA - you got this? You don't need to get paid. The pay off is in the results. That's why we pay dues.
