The U.S. Supreme Court has to decide today whether the ban on handguns is constitutional or not. District officials say that the Supreme Court has to decide if the Washington DC’s ban on handguns respects the Constitution.

According to BBC, the ban is 32-year-old and the Supreme Court is to tell if the Second Amendment protects an person’s right to possess a gun or if it gives the state the right to organize armed militias.

While DC city council said that the ban is necessary in order to keep under control violence, Dick Heller, a security guard, challenged the ban, saying he should have the right to possess a gun for his self-protection. In March, a federal appeals court said Heller was right and the Second Amendment protected an individual’s right to own a gun, making the DC ban unconstitutional.

The city took the case to the Supreme Court and it remained to see what the decision would be.

The opinions are divided as there are groups who agree with the ban and others who say the ban should be removed. In case the Supreme Court upholds the ban, it is possible that other gun laws in other parts of the U.S. would be challenged.

A survey has showed that there are 90 guns for every 100 citizens, but there are persons who own more than one gun and others who own none.
