Good morning, Bulletin readers. A gun rights rally at the Virginia Capitol attracted heavily armed extremists but ended without the bloodshed some had feared. But as activists were protesting the prospect of new restrictions and safety laws, families across the country were reeling from multiple-casualty shootings.

WHAT TO KNOW TODAY

NEW from THE TRACE: Sound, fury, but no violence as thousands protest new gun laws in Virginia. Opponents of tougher gun laws chanted slogans, hoisted signs, and vowed to defend the Second Amendment at a rally in Richmond, Virginia, on Monday that many on both sides of the gun debate had feared would attract extremist violence. While the worst-case scenario did not materialize, militia members and white nationalists openly carrying assault-style rifles and clad in full battle gear did steal some of the spotlight from the pro-gun activists who had hoped to distance themselves from the fringe elements who were also drawn to the event. Authorities estimated the crowd, which skewed heavily male and white, at 22,000. Here’s Will Van Sant’s dispatch from the scene.  

Shootings across the country on Sunday left dozens injured. Sixteen people were shot, one fatally, when someone opened fire outside a bar in Kansas City, Missouri. Officers said the shooter started firing during a fight and was shot and killed by an armed security guard. Raeven Parks, 25, died in the incident. Three of the survivors are in critical condition. In San Antonio, seven people were shot, two fatally, when an argument escalated to gunfire at an area bar. The fatalities were identified as Robert Jay Martinez III, 20, and Alejandro Robles, 25. In Honolulu, two police officers were killed after responding to a stabbing at a home. The suspected gunman, who had reportedly attacked his landlord after receiving an eviction notice, then set fire to his and several other homes, police said. Honolulu’s police chief identified the victims as Kaulike Kalama, a nine-year police veteran, and Tiffany Enriquez, a seven-year veteran. They were both parents.

A Utah teen fatally shot four members of his family. A fifth person was wounded in the Friday incident in the town of Grantsville, about 40 minutes southwest of Salt Lake City. “Our hearts are broken by the horrible news,” Utah Governor Gary Herbert tweeted, adding, “Parents and grandparents, secure your firearms! Everyone, hug your loved ones tight. And remember love, not hate, will heal broken individuals and families.”

Temporary gun dealer security rules went into effect in Illinois. The requirements stem from a new law that aims to curb the diversion of firearms into the black market. As of Friday, gun stores are required to have alarm systems capable of notifying law enforcement in the event of a break-in and to track sales using an electronic record-keeping system. Todd Vandermyde, a former National Rifle Association lobbyist who now heads Federal Firearms Licensees of Illinois, told The Trace’s Brian Freskos that some of his group’s members are hesitant to bring themselves into compliance for fear that security upgrades won’t satisfy the final requirements that the Illinois State Police are expected to release later this year: “How are you supposed to comply with a new law when you don’t even know for certain what the standard is?”

Washington State plans to sue the Trump administration over 3D-printed guns. Bob Ferguson, the state’s Democratic attorney general, said he will be leading a 21-state coalition when he files the challenge to a Trump administration rule, finalized on Friday, that would transfer regulatory authority of 3D-printed guns and other firearms from the State Department to the Commerce Department. Critics say the move would make it much easier to publish and share schematics for 3D-printed guns — which have no serial numbers, making them impossible for law enforcement to trace.

A bipartisan bill in Arizona would close the “boyfriend loophole.” The legislation, filed in the GOP-led state House and Senate, subjects abusive dating partners to a gun ban. Federal law only applies a domestic violence gun ban to abusive spouses, co-parents, parents, or live-in partners. The proposal also provides a procedure for the surrender of guns by convicted abusers.

DATA POINT

Gun violence rose by more than 40 percent in Canada in the five years after the national gun registry was dismantled in 2012. The country imported nearly two million American guns during that period. NPR
