Paul Birdsong leads the Black Lion Party for International Solidarity, an armed, Black Panthers-inspired mutual aid group in Philadelphia.
Until February, the 39-year-old carried a firearm during the group’s neighborhood patrols to increase neighborhood safety. Then the police revoked his carry license. Four other Black Lion members lost their licenses the same week.
The city’s revocation letters, by published accounts, explained little. They cited “good cause” and Birdsong’s “character and reputation.”
They also pointed to a tense January 2026 encounter between a group of Black Lion members carrying rifles and a group of officers. The argument at a snowy intersection at 23rd and Diamond streets in North Philadelphia ended in hard words – but no arrests, citations or violence.
On June 9, 2026, the U.S. Department of Justice opened a civil rights investigation into the Philadelphia Police Department’s licensing practices.
Assistant Attorney General Harmeet Dhillon wrote to Philadelphia Mayor Cherelle Parker that her office would examine whether the Philadelphia police can use a “vague ‘good cause’ standard” to cancel permits.
The Justice Department’s press release stated the rule directly: “It is a violation of the Second Amendment for government officials to use vague, personal discretion when determining whether to issue or revoke permits to carry firearms.”
Philadelphia’s unique gun laws
The prevalence of guns in Philadelphia has real public safety stakes. Gun violence in Philadelphia has fallen from its COVID-19 pandemic-era peak, when there were 562 gun homicides in 2021, but the problem remains serious.
As of late June 2026, city data shows 330 people were shot in Philadelphia so far this year, 71 of them fatally. Parker has made violence reduction central to her agenda. That context helps explain why officials may seek aggressive tools, even as the U.S. Constitution limits their discretion.
We are scholars of gun laws and the Second Amendment. One of us is a law professor at the University of Wyoming, co-author of “Firearms Law and the Second Amendment: Regulation, Rights, and Policy” and an unpaid trustee of the National Rifle Association’s Civil Rights Defense Fund. The other is a law lecturer at the University of Pennsylvania who has taught firearms law across the state and country and is a board member of the National Rifle Association, and who has also represented the organization on a variety of matters prior to becoming a board member.
Philadelphia has long been the outlier in Pennsylvania when it comes to public carry. Public carry refers to legally carrying a firearm in public places, whether openly, where the gun is visible, or concealed, where the gun is hidden from public view. Pennsylvania adults may lawfully carry firearms openly without a license everywhere but in the city of Philadelphia. Statewide, a license is always required to carry concealed.
In Philadelphia, however, gun owners need a license to carry openly too. This exception is rooted in the Pennsylvania legislature’s public policy choices made decades ago.
But this Philadelphia-only firearms rule is under constitutional pressure. In 2025, in Commonwealth v. Sumpter, the Superior Court of Pennsylvania held it unconstitutional as applied. The state Supreme Court is now weighing the question.
Yet, for now, the statute remains on the books and still lets a license be revoked for “good cause” or because an official deems the holder’s “character and reputation” dangerous.
The Department of Justice says that’s a problem.
Supreme Court ruling on gun licenses
To understand the Department of Justice’s case against Philadelphia, it’s helpful to look back to 2022, when the U.S. Supreme Court decided New York State Rifle & Pistol Association v. Bruen.
In its 6-3 ruling along what are considered typical conservative-liberal lines, the court struck down a New York law that issued carry licenses only to applicants who showed special “proper cause.”
The court drew a clear line. A government may screen permit holders with “narrow, objective, and definite standards” – a background check, a safety course, fixed criteria an honest applicant can know and meet. What the government may not do, the justices ruled, is hinge the right on “the appraisal of facts, the exercise of judgment, and the formation of an opinion.”
The majority added in its ruling, “We know of no other constitutional right that an individual may exercise only after demonstrating to government officers some special need.”
Justice Brett Kavanaugh condemned “open-ended” and “unchanneled discretion for licensing officials.”
The dissent saw it differently. Justice Stephen Breyer, joined by Justices Sonia Sotomayor and Elena Kagan, argued the court should have considered “the State’s compelling interest in preventing gun violence and protecting the safety of its citizens.” In that view, dense urban risks justify more room for local judgment.
But Bruen rejected that approach and ruled that the government’s interest in preventing violence cannot justify vague or open-ended discretion over who may exercise a constitutional right.
The problem with ‘good cause’ standards
If someone in Philadelphia wants to carry a gun, they must obtain a license to carry through the Philadelphia Police Department’s gun permit unit. But without an objective yardstick, two police officers can review the same file and make opposite decisions about the granting of a license.
With a subjective standard, an applicant who is quiet, polished and familiar to the licensing office may pass this test, while another who is equally law-abiding but perhaps less polished or more socially awkward may fail.
One officer might treat a passionate social media post as proof of instability; another might treat it as protected speech.
A rule-bound system asks whether the applicant is legally disqualified. A discretionary one asks whether the official is comfortable with the applicant.
That is how a constitutional right impermissibly becomes a discretionary privilege.
Suppose you could vote only if a clerk judged an applicant’s “character and reputation” sound. Suppose a parade permit could be revoked whenever the marchers’ conduct “troubled” police. That would be intolerable in any other setting – not because every voter or marcher is admirable, but because constitutional rights are not based on a government employee’s benevolent opinion.
Whether someone supports the Black Lions or finds their armed patrols unsettling is beside the point. When the test for stripping a right is “good cause” – words that mean whatever the person holding the stamp wants them to mean – the test itself violates the Constitution.
Other cities, including New York City and Boston, also administer gun-licensing systems with subjective moral-character or suitability standards. However, Pennsylvania’s “character and reputation” language is among the most open-ended, particularly as it relates to the revocation of licenses.
Whatever happened at 23rd and Diamond streets, the dispute is relevant to every gun permit holder in the city: May one of the largest police forces in the country switch a constitutional right on and off according to its own read of a person’s perceived suitability or reputation?
