Should nation reinstate assault weapons ban?

Not surprisingly, the Colorado movie theater shooting has renewed debate about whether the public should be able to buy assault weapons. Mitt Romney is opposed to new gun laws, though he signed an assault weapons ban when he was governor of Massachusetts, describing such guns as “instruments of destruction.” He also wrongly said that the Colorado suspect possessed the guns illegally. The White House said that President Obama would not pursue new gun laws, though Obama called Wednesday for stepped-up background checks and restrictions to keep mentally ill people from buying weapons.
