Democratic controlled cities like Washington DC and Chicago have made numerous attempts to impose strict gun control measures, some of which are unconstitutional.
In 2008, the US Supreme Court ruled against one of those unconstitutional gun control measures in Washington DC. In the case of Heller v. District of Columbia, the Supreme Court ruled that the DC ban on handgun ownership violated the Second Amendment right to self-defense of DC citizens. In this case Justice Scalia rendered the majority opinion in which it was stated in part:
“1. The Second Amendment protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home…”
“2. Like most rights, the Second Amendment right is not unlimited. It is not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose: For example, concealed weapons prohibitions have been upheld under the Amendment or state analogues. The Court’s opinion should not be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms. Miller’s holding that the sorts of weapons protected are those ‘in common use at the time’ finds support in the historical tradition of prohibiting the carrying of dangerous and unusual weapons.”
