As the sun rose Monday, about 80 law officers gathered with “game day” enthusiasm, ready to fan out across metro Atlanta and round up bad guys.

Or what Deputy U.S. Marshal Gavin Duffy called “guys with a paradigm for violent crime.”

The marshals’ Southeastern Regional Fugitive Task Force had arrest warrants for 40 suspected gang members on charges ranging from minor probation violations to hard-core felonies. By Thursday afternoon, about 30 gang members were in custody as well as another dozen of their associates found with guns, drugs or their own pending warrants, marshals said.

“We have zero tolerance toward gangs,” Duffy said in a pep talk. “Any violation of the law, people go to jail today.”

The task force, comprising marshals, Atlanta police and other law officers, was timed to coincide with the murder trial of a suspected 30 Deep gang member in Fulton County Superior Court. Operation Zero Deep targeted that gang, as well as others.

Nationally, the U.S. Marshals Service has been teaming up with local agencies to round up fugitive gang members to disrupt their activities and help police identify the fugitives’ associates. It’s almost like an armed census.

“These guys aren’t hanging out with choir boys — they’re hanging out with gang members,” task force commander Keith Booker said. “We conducted numerous interviews with these guys during the operation so we’ll have a database we can go to.”

The teams of heavily armed agents rolled into neighborhoods in convoys of SUVs, hoping to catch gang members at home. But the mission’s logistics curbed much of the surprise. Atlanta police Sgt. Jeffrey Branum, a gang unit supervisor, nodded toward young people on cell phones as his convoy turned off Cleveland Avenue — the territory of Raised on Cleveland, a subset of 30 Deep. “They probably already know we’re here,” he said.

The first raid was a bust — initially. The team fanned out around a tiny house and knocked on the door, while a marshal pointed an AR-15 at a front window. A man answered and marshals Supervisor James Ergas politely asked for permission to check the house. A man said the ex-con was not there but might be at his girlfriend’s in Atlanta’s Pittsburgh neighborhood near Turner Field, home turf for 30 Deep.

As team members planned the next raid, they learned one of their 40 targets was strolling up the street toward them. An Atlanta officer couldn’t believe a wanted suspect could be so clueless as a sleepy-eyed Jason Scott looked up, wondering what all the fuss was about. “Talk about walking into a hornet’s nest,” the officer said to a gale of laughter.

The officers had a warrant for Scott, originally arrested in September for burglary, auto theft, robbery and smash-and-grab thefts and released from jail in November, according to Fulton County records.

Throughout the day, some neighbors saw the show of force as overkill. “What did he do, shoot the president?” asked Kenny Johnson, while watching the task force arrest a man in south DeKalb County.

The arrested man, a gang member not on that day’s wanted list, had a warrant from Baltimore on a murder charge. Johnson was surprised to hear that. “We know his mother,” he said.

Ergas said a show of force almost always results in safer operations. “That is why we hardly ever get into any shootings,” he said. “People who think, ‘I might try two police officers if I had a gun,’ see that it is for real. You eliminate the danger.”

Still, a day later, two deputy marshals in St. Louis were shot, one fatally, while trying to capture a suspect.

Late Monday afternoon, residents of a Thomasville Heights apartment complex emptied out of their homes to watch task force members run between the buildings and over the worn lawns. Special Deputy Marshal Josh Thompson and his men headed to Unit 59 hoping to nab Antwuan Cook, believed to be associated with the Pittsburgh Gangsters. He had Atlanta arrest warrants and a Gwinnett County probation violation, officers said.

A pair of blue sneakers hung by the laces over a nearby utility wire, marking gang territory. The complex, officers said, is home turf to gang members who identify with the national Crips, whose color is blue.

Cook wasn’t home. An informant said they missed him by minutes. Instead, the raiders found Mario Miller, 24, and Reid Nowell, 31, and about 2 pounds of marijuana being bagged for sale. In the apartment agents found a photo of Cook posing with an AK-47.

Thompson questioned Miller as he sat handcuffed on the stoop in a navy blue hoodie. Records indicate he has arrests for armed robbery, aggravated assault and carjacking. He got out of prison Feb. 2, having served less than two years of sentences that included 10 years for two aggravated assaults and five years for an attempted armed robbery, according to prison records.

Thompson, a parole officer, noted Miller already violated his probation by failing to report — not to mention being around a pile of weed. Officers hope this arrest will send Miller back to prison.

Thompson checked Miller’s cell phone and the words “Crips Cartel” popped up on the screen. “Man, I’m just an ordinary person,” Miller said when the deputy asked about the reference.

While the task force wrapped up, some kids kicked a soccer ball and others frowned and stared as the neighborhood gathered to watch.

Hard looks are not unusual, parole officer Rodney Akins said.

“We’re the bad guys and they’re taught that from this old,” Akins said, holding his hand three feet off the ground. “I’m glad my mother taught me different.”

COMING SUNDAY

Atlanta-based 30 Deep is much on the minds of local law enforcement. Who is 30 Deep? Where did it come from? And what are police doing to tamp down potential threats from this gang?
