The day before the US Supreme Court struck down the constitutional right to abortion, it affirmed the right to carry guns.

Why?

New York Times columnist Emily Bazelon explains that the justices think that the right to bear arms is enshrined in the 2nd Amendment is individual and rooted in the nation's history and tradition, while abortion is neither.

The thing is, she tells Ian Bremmer on GZERO World, "the interpretation of the 2nd Amendment that they claim is rooted in the nation's history and tradition is actually correct."
