No one would own handguns in a perfect world, several Democratic presidential hopefuls believe.

“In an ideal world, people would not own handguns, and there are a number of countries around the world where people do not own handguns.” said Julián Castro, former secretary of Housing and Urban Development told the New York Times. Castro acknowledged, however, that there is a constitutional right to bear arms and suggested reforms such as gun buybacks and universal background checks to address gun violence.
