States with strict gun laws have lower rates of gun deaths among children and teenagers, and laws to keep guns away from minors are linked with fewer gun suicides in this age group, a Stanford study found. Compared with U.S. states with the strictest gun control legislation, gun deaths among children and teenagers are twice as common in states with the most lax gun laws, a study from the Stanford University School of Medicine has found.

Manufacturing errors, undetected by inexpert consumers, may be more dangerous than other threats from 3D-printed guns.

In 2016, the last year for which the CDC provides numbers, 35,353 people died from gun injuries, the majority of them suicides. In other words, out of every 100,000 people living in the US that year, 12 were killed by a gun, compared to 11 in 2015 and 10 in 2014. “But mortality rates don’t show you how much of your life is lost,” says Bindu Kalesan, a Boston University assistant professor of community health sciences. “Who is dying young, and who is dying old?”

A Florida police officer is facing mounting backlash over a Facebook comment in which he seemingly wished violence upon Parkland shooting survivor David Hogg and other young gun control activists.

For more than a year, Florida failed to do national background checks that could have disqualified people from gaining a permit to carry a concealed weapon. The lapse, revealed in an internal report that was not widely known about until Friday, occurred during a time period when there was a significant surge in the number of people seeking permission to legally carry a concealed weapon. Florida does not allow the open carry of weapons, but more than 1.9 million have permits to carry guns and weapons in public if they are concealed.

For more than a year, the state of Florida failed to review national background checks on tens of thousands of applications for concealed weapons permits, potentially allowing drug addicts or people with a mental illness to carry firearms in public.

A Chinese firm wants to arm the country's police forces with a whole new kind of weapon for the battlefield: an assault rifle that fires lasers and can burn your clothes and skin from up to 800m away. Oh, and those lasers are silent, invisible, and can pass through glass windows too.

The suit also names Seattle Mayor Jenny Durkan, the Seattle Police Department and Chief Carmen Best. Durkan reacted to the suit Friday, “While they go to court – kids go to the hospital. We can’t prevent every gun death or injury, we can take steps to help prevent tragedies. I am grateful that legal experts who share our commitment to reducing gun violence are standing with us and standing up for safer communities.”

A new legal filing by the powerful gun group against the state of New York paints a grim picture.

Hunting is possibly the proudest outdoor tradition our country has: It’s why we have such abundant animal populations. It’s how millions of American families put affordable healthy protein on their dinner plates. And, in large part, it’s what pays for the rest of us to enjoy so much wild land. That’s why it’s unconscionable that the NRA uses hunting as an excuse to pollute American politics with its toxic agenda.

How many times per year does a gun go off in an American school? We should know. But we don't. This spring the U.S. Education Department reported that in the 2015-2016 school year, "nearly 240 schools ... reported at least 1 incident involving a school-related shooting." The number is far higher than most other estimates.

The state's insurance agency sent a cease-and-desist order, saying the NRA isn't licenced to sell the product

As Las Vegas prepared to honor those killed in last year's shooting massacre at a country music festival, the federal government moved ahead Monday with plans to ban an accessory that investigators said gave the gunman extra firepower.
