The mass murder of elementary school children in Connecticut has angered many Americans who want to end the virtual free-for-all that is that country's gun laws.

After decades of easing restrictions on firearms, Heidi Rathjen of the Quebec Coalition on Gun Control thinks this mass murder -- one of several this year in the United States -- may be the tipping point.

"If the death of 20 innocent children doesn't make a difference, nothing will," said Rathjen.

"Barack Obama has come out stronger than he ever has, saying something, even though he wouldn't utter the words 'gun control' and the reaction has been much more swift and focused in terms of calling for gun control... This time people who support gun control, whether it's ordinary citizens or other politicians or mayors, they have come out very strongly right away," said Rathjen.
