A Landmark Judgement

On june 23, 2020 the United States Supreme Court gave a landmark decision in the case widely known as New York State Rifle & Pistol Association, Inc. v. Bruen. The judgment ruled New York's law was unconstitutional, and effectively ruled that the possession of pistols in public was a constitutional right under the Second Amendment. It was a case challenging the new york states law that requires you to have a proper cause in order to carry a concealed pistol on their person in public. After this historic judgment, support and backlashes came up all across the US.

Gun VIolence

Gun-related violence is a violence committed with the use of a firearm. This includes criminal violences such as homicide, assault with a deadly weapon, and suicide, or attempted suicide, where any kind of firearm is used. According to the United Nations, deaths from small firearms exceed those from all other weapons combined, and more people die each year from gun-related violence than did in the atomic bombings of Hiroshima and Nagasaki combined. The global death toll from use of guns may be as high as 1,000 deaths each day.

Here, through the above graph we can clearly say that the USA is the only country with higher income but still is amongst the top countries with gun violence. The other countries considering the yearly GDP are still low income countries when compared to that of the United States.

USA and Firearms

Every US citizen has a birth right to own firearms according to the second amendment. So, many carry guns for self-defense. But this also means anyone and everyone has equal access to guns. US governments have allowed gun violence to become a human rights crisis. On average, more than 360 people in the USA are shot every day and survive, at least long enough to get to a hospital.

"A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."

For increasing such restrictions and implementing more laws for obtaining and Licensing a gun, the members of congress have to pass and vote on legislation. So, both the gun rights and gun control organizations do lobbying as well as outside spending.

Lobbying: organisations pressurize law makers by conducting mass public events.

Outside Spending: Political action committee provide funds for Election spending to gain their support.

So, from all this we can clearly understand that the gun rights organization spends more every year for lobbying and outside spending to push lawmakers into either postponing or rule out gun control laws and restrictions. And this is only increasing every year.
