New legislation in front of Congress would make it legal to carry a concealed, loaded firearm from any state into any other, regardless of local laws governing concealed carry or gun ownership.

Moreover, he fears, targeted cities such as New York will be more vulnerable to attacks from homegrown violent extremists. With deadly gun violence continuing to make national headlines, can we have a national conversation about what makes sense?
