In a speech at a memorial in Newtown, Connecticut on Sunday, President Obama vowed to use the power of his office to prevent future mass killings. But he stopped short of mentioning any specific proposals. Gun control advocates, including California Senator Dianne Feinstein -- who has said she will push for a new assault weapons ban -- are calling on the president to act. But supporters of gun rights say that new laws are not the answer, pointing out that Connecticut already had tough firearm regulations.
