Is it time to rethink gun legislation?

      The 2nd amendment gives Americans the right to bear arms.{} There are an estimated 200 million-plus guns in circulation in this country, but now, some are calling for tighter restrictions on who can get access to them.

      Sen. Joe Manchin, a lifelong member of the National Rifle Association, says it's time to discuss gun policy and move toward action on gun regulation.{} It, of course, follows the school shooting in Connecticut that killed 20 children.

      The conservative West Virginia Democrat agreed with New York City Mayor Michael Bloomberg, who{}has advocated banning the sale of assault weapons.{} "I don't know anyone in the sporting or hunting arena that goes out with an assault rifle. I don't know anyone that needs 30 rounds in a clip to go hunting," said Manchin.

      Manchin{}is the most prominent gun rights advocate to speak publicly in the wake of the shooting.

      On Sunday, President Barack Obama never used the word gun, but he issued an emotional and unspecific call to action.{}{} "We can't tolerate this anymore. These tragedies must end. And to end them we must change," the President said.

      So far the National Rifle Association has been silent.{}{}It hasn't tweeted since{}Friday's shooting. and{}its Facebook page has been taken down.{}{}
