WHAT TO KNOW TODAY

Seven people were shot in a gambling den in New York City. Four men were killed and three others were wounded in a shooting at an unlicensed social club in Crown Heights, Brooklyn, early Saturday morning. The dead range in age from 32 to 47. Police believe the gunman was among the fatalities. In July, a dozen people were shot at a Brownsville, Brooklyn, block party, an incident overshadowed in media coverage by a mass shooting that same weekend at a California food festival.

Five people were fatally shot by a disgruntled neighbor in Chicago. Three women and two men were killed when a man opened fire on two units of a condominium in the city’s Dunning neighborhood on Saturday evening. The victims range in age from late 30s to late 60s. The suspect, a 66-year-old construction worker, is in custody.

Six people were wounded in a drive-by shooting in Philadelphia. The youngest victim of the incident on Sunday was 14. Police do not have a suspect or a motive.

Two people were shot at a wedding in a New Hampshire church. A bishop, 75, and the bride, 60, were wounded when gunfire broke out at the Saturday morning service. Several wedding guests tackled the shooter, who was arrested.

A 2-year-old boy was wounded in a road rage shooting in Baltimore. The driver of the car carrying the toddler had been honking at motorists idling at a green light on Saturday. One of the drivers opened fire, hitting the child in the stomach. He is expected to survive.

A white police officer in Texas killed a black woman in her own home. The officer entered the Fort Worth home of Atatiana Jefferson, 28, early Saturday after her neighbor called the non-emergency line of the local precinct and asked for a wellness check because Jefferson’s door was open. Body camera footage shows the officer saying “Put your hands up! Show me your hands!” — but not identifying himself as law enforcement — before firing a single shot. Jefferson is the sixth person killed by Fort Worth police since June.

The federal government is quietly dropping its case against a California man who illegally manufactured AR-15s. Joseph Roh ran a black-market factory that sold firearms to more than a dozen people banned from owning guns, including a man who went on a deadly shooting rampage in Santa Monica in 2013. CNN has a deep dive into how a case that looked like a slam dunk instead resulted in a settlement deal. The upshot: Roh’s defense attorney convinced a judge that the Bureau of Alcohol, Tobacco, Firearms and Explosives has improperly classified the AR-15 part — the lower receiver — central to Roh’s scheme: The bureau treats the components as guns, since they can easily be built out into functioning firearms. But the AR-15 lower receivers Roh was using don’t fit the technical specs spelled out in the federal code. Federal prosecutors dropped the charges rather than set a precedent that “could open up a huge loophole in federal law,” as one legal expert put it.

California is getting several more gun safety laws. The legislation signed by Democratic Governor Gavin Newsom raises the age to buy guns to 21; establishes a one-gun-per-month limit for long guns; requires more gun sellers to get a license; requires a background check to buy ghost gun parts; and expands the state’s red flag law to let employers, co-workers, and teachers ask a judge to disarm potentially dangerous people. The American Civil Liberties Union opposed the red flag law expansion because it doesn’t let gun owners argue their side before their guns are seized.

The Oath Keepers plan to patrol another Trump rally. The anti-government militia, which called on members to escort Trump supporters at a rally in Minneapolis last week, plans to do the same in Dallas on Thursday.
