From The Washington Post:

A federal judge ruled Tuesday that a key provision of the District’s new gun law is probably unconstitutional, ordering D.C. police to stop requiring individuals to show “good reason” to obtain a permit to carry a firearm on the streets of the nation’s capital.

U.S. District Judge Richard J. Leon found that the law violates the “core right of self-defense” granted in the Second Amendment, setting aside arguments from District officials that the regulation is needed to prevent crime and protect the public.
