Pennsylvania's proposed disease regulations are being read as a response to measles. Stakeholder meetings were held in 2024. The Advisory Health Board approved them in July 2025. The drafting predates the outbreak by two years. triblive.com/opinion/edit...

Editorial: Did Pennsylvania learn from the last outbreak?

The Pennsylvania Department of Health wants to stretch its muscles with regard to its ability to investigate public health emergencies and disease. It’s an idea that might be worrisome if you ar...

Regulating civilian concealed gun carrying is different than most other gun laws. But our research at Johns Hopkins has shown that higher standards for who can carry a gun around are most effective and are widely supported by gun owners in our surveys.

www.nytimes.com/2026/08/27/o... This is a well-crafted piece informed by the sociologist’s research studying guns in our US society. But I push back on the characterization of gun regulation as being about keeping ppl from buying guns. Most gun control laws are about keeping guns from violent ppl.

Baltimore ranks No. 2 on Violence Prevention Index — but the score has a catch I was happy to share my thoughts w/ the reporter for this story. Knowing the Sinclair News audience, the headline and other parts highlight uncertainty and downsides of Baltimore’s incredible success in reducing homicides

This is an important case. Demonstrates multiple ways that illegal straw purchasers signal their intentions to sell or transfer their guns to people who can’t legally purchase guns. Dealers can spot these, deny the sale and report it to law enforcement. Make the dealers pay if they don’t.

Fleet Farm in Blaine, Minnesota sold a Mossberg MC2c pistol to a man who bought over two dozen guns from the store in just four months, including eight in a single week. The pistol was later used in a mass shooting that killed one woman and wounded 14 others.

This list - at least the big trucks - is not a surprise. Aside from the size, power, and design, I find that the drivers of these trucks tend to be the most aggressive. They know they’re the big dogs on the road and exert their dominance despite the danger that they are creating for others.

Important move by Gov Hochul in the wake of the Trump Admin planned rollbacks on gun seller regulations and oversight, green lighting internet sales and delivery to your door (what could go wrong?) and eviscerated capacity in combating gun trafficking. govwesmoore.bsky.social @abigailspanberger.com

Our deepest gratitude to @governor.ny.gov Kathy Hochul for stepping in to protect public safety as the Trump administration continues its attack on federal gun safety regulations. Her leadership should inspire other governors to take action to protect their communities.

www.thetrace.org/2026/07/balt... Excellent article describing how Baltimore dramatically reduced homicides since 2022. Kudos to UPenn’s Ben Struhl & Jeremy Biddle, MONSE’s Stefanie Mavronis, Police Commissioner Worley, Safe Streets, Roca, YAP. Focus on the highest risk w/ supports & accountability.🙌

What Can Cities Learn From Baltimore’s Extraordinary Decline in Violence?

A growing body of research suggests that the city’s approach to reducing shootings at scale may be one of the most effective yet.

Washington Post gives brief quote from former ATF official explaining how dangerous the proposed rule is to the public near the end of the article. Disappointing that such an insane proposal threatening public safety is casted as normal evolution of a marketplace for consumer convenience.

Plan to ease rules on mailing guns could help company Trump Jr. has stake in Long article with ~10 quotes from the Trump Admin and the gun lobby claiming current regs prohibiting online sales of guns violate the 2A. No counter from Constitutional scholars. More $ for gun industry, more deaths.

Requiring 3D printer makers to not allow their product to make firearms is common sense. Sales of DIY ghost gun kits were gas on the fire of the surge in gun violence in 2020 and their regulation has likely contributed to historic reductions since 2022. GVP advocates make this a priority.

"The number of privately made guns recovered in crimes and submitted to federal authorities rose from about 1,600 in 2017 to nearly 27,500 in 2023."

By freeing up licensed dealers who don’t comply with federal law to divert guns to traffickers, other criminals, and underage youth, it increases gun sales and profits. More gun crime boosts civilian demand for guns. They want everyone armed at all times.

That the Trump Admin is changing its policies to suit industry, especially the gun industry, rather concern itself with the safety and welfare of Americans is no shocker. These moves have nothing to do with 2A rights and everything to do with what Trump values - $ and power.

They’re saying the quiet part out loud: The only federal agency tasked with enforcing our nation’s gun laws is now shielding gun dealers who violate federal law.

Elon Musk’s DOGE cut the federal government’s screwworm monitoring program, which cost $15 million. Now, the Trump administration is preparing to spend $1 billion to combat the screwworm outbreak. Never forget how destructive and downright stupid DOGE was.

Gun dealers who had their licenses revoked for noncompliance are not just allowed to reapply, they are encouraged to reapply. And those noncompliant dealers will face no oversight because a) many ATF agents who work compliance have resigned or been reassigned and b) supervisors got the message.

www.propublica.org/people/alec-... Sharing this excellent article that describes the many things that the Biden Admin was doing to combat illegal gun trafficking including crackdowns on gun dealers not complying with the law. No surprise, Trump has dismantled everything in a favor to the industry.
