What Is Gun Control and Why Cant America Pass It?

The numbers on American gun violence are not disputed. The US has far more guns, far more gun deaths, and far more mass shootings than any comparable wealthy nation. And the political system has, for decades, been unable to pass meaningful reforms despite consistent majority public support for them.

Understanding why requires looking at structure, not just sentiment.

The Scale of the Problem

The US has approximately 400 million civilian-owned guns — more than one per person, and more than any other country by a significant margin.

Annual gun deaths: approximately 45,000-48,000.

• Suicides: about 54% — the US gun suicide rate is dramatically higher than other countries
• Homicides: about 43%
• Accidents, law enforcement, undetermined: about 3%

Gun death rate comparison per 100,000 population:

• United States: ~12
• Canada: ~2.1
• Australia: ~1.0
• Germany: ~0.9
• United Kingdom: ~0.2

Mass shootings — defined by the Gun Violence Archive as incidents with 4+ victims — number in the hundreds per year in the US. The definition, measurement, and comparison to other countries involves genuine methodological debates, but no methodology produces a number close to peer nations.

Why the Senate Doesn't Act

Public polling consistently shows 70-90% of Americans support universal background checks for all gun sales and 60-75% support red flag laws (allowing courts to temporarily remove guns from people judged to be dangers to themselves or others).

These policies would pass easily if Congress voted by simple majority. They don't pass because:

The filibuster requires 60 Senate votes. Republican senators — even those whose constituents support background checks — face a structural reality: gun rights groups score votes and mobilize single-issue voters. The NRA and related organizations spend heavily on primaries. Breaking with gun rights orthodoxy risks primary challenges in Republican-leaning states.

Senate geography. Each state gets two senators regardless of population. Rural states — where gun culture and gun ownership rates are highest — are disproportionately represented in the Senate relative to their population. Wyoming and California both get two senators. This gives rural gun-owning constituents structural veto power over gun legislation.

2022 was the exception. The Bipartisan Safer Communities Act passed in June 2022, weeks after the Uvalde elementary school shooting. It was the first significant federal gun legislation in 28 years. It included: enhanced background checks for buyers under 21, closing the "boyfriend loophole" (domestic abusers who weren't married to victims could previously pass background checks), incentives for states to adopt red flag laws, and funding for mental health services. Important — but far short of universal background checks or an assault weapons ban.

The Constitutional Landscape After Bruen

The Second Amendment landscape has been significantly reshaped by the Supreme Court.

Heller (2008): Established that the Second Amendment protects an individual right to keep arms in the home for self-defense. This ended the debate over whether the amendment applied to individuals or only militias.

McDonald (2010): Extended Heller's protections against state and local laws.

Bruen (2022): Established that gun regulations must be "consistent with the nation's historical tradition of firearm regulation" — meaning regulations must have analogues from the Founding era (1791) or Reconstruction era (1868) to be constitutional. This is a dramatically stricter test that has led multiple federal courts to strike down regulations that previously would have passed.

Post-Bruen, courts have struck down or questioned regulations on: people with domestic violence restraining orders, people who use marijuana, people with misdemeanor convictions, and various other categories. The Supreme Court in 2024 reversed the domestic violence ruling, holding that the protection from Heller didn't extend to people currently subject to domestic violence orders. But the litigation landscape remains extremely active.

What Research Actually Shows

The research on gun control effectiveness has historically been underfunded — Congress banned CDC research on gun violence from 1996 to 2020 under the Dickey Amendment. Research that exists shows:

• Background checks have prevented millions of prohibited person gun purchases
• Red flag laws are associated with reduced suicide rates
• State-level assault weapons bans correlate with lower mass shooting death rates
• The private sale loophole allows approximately 22% of gun acquisitions to bypass background checks

Australia's response to its 1996 Port Arthur massacre — mandatory buyback of semi-automatic rifles, tightened licensing — is cited as evidence that policy can dramatically reduce gun violence. Australia has had no mass shootings (by the Australian definition) since the buyback. Critics note Australia's lower baseline gun ownership made buyback more feasible.

The US context is different: 400 million guns already in circulation, a constitutional right to possession, and a deeply embedded gun culture create policy constraints that don't exist in Australia. What's possible in the US is meaningful reform at the margins. Whether those margins save lives — and the evidence suggests they do — is the practical policy question.
