PROBLEM: Walmart has joined Dick's Sporting Goods in raising its age restriction for the purchase of firearms to 21 years old  the Bentonville  Arkansas-based mass retailer announced Wednesday night.
Walmart's announcement comes the same day that Pittsburgh-based Dick's Sporting Goods Inc. made a similar move. It said it was ending sales of assault-style rifles  banning the sale of guns to people younger than 21  and ceasing the sale of high capacity magazines.
"Based on what’s happened and looking at those kids and those parents  it moved us all unimaginably  " Dick's Sporting Goods Inc. chairman and CEO Edward Stack  said Wednesday on "Good Morning America."
 He  added  "To think about the loss and the grief that those kids and those parents had  we said  'We need to do something.' And we’re taking these guns out of all of our stores permanently."
Despite the moves by  Dick 's Sporting Goods and Walmart  most firearms are not sold at outdoor specialty retailers like  Dick’s   according to a survey by Fernandina Beach  Florida-based Southwick Associates  a market research firm that specializes in the hunting  shooting  sportfishing  and outdoor recreation markets.

SOLUTION: Dick

PROBLEM: French Prime Minister Francois Fillon and President Hamid Karzai spoke to journalists in the capital of Kabul after meeting earlier in the day. They discussed the recent international conference on Afghanistan in London and the need to push forward with plans to reconcile Taliban fighters with the government  Fillon said.
 "The French support is something that you can enjoy and France will remain in Afghanistan for as long as it takes " Fillon said  but added that France has no plans to expand its military effort.
 France has about 3 750 troops in Afghanistan  most in the mountainous east. The country increased its presence considerably in 2008  Fillon said.
 "We have a mission to fulfill  the mission that has been negotiated with our allies " Fillon said. "We consider that the resources that we have here are sufficient to reach that objective and fulfill that mission."
 Fillon said he would also be visiting French troops. Embassy officials could not be reached for further comment.

SOLUTION:
Fillon
