SAN DIEGO (AP) — The U.S. Border Patrol on Tuesday unveiled its first national strategy in eight years, a period in which the number of agents more than doubled and apprehensions of people entering illegally from Mexico dropped to a 40-year low.

The new approach — outlined in a 32-page document that took more than two years to develop — uses buzzwords like “risk-based” and “intelligence-driven” to describe a more nuanced, targeted response to constantly evolving threats.

The Border Patrol previously relied on a strategy that blanketed heavily trafficked corridors for illegal immigrants with agents, pushing migrants to more remote areas where they would presumably be easier to capture and discouraged from trying again.

“The jury, for me at least, is out on whether that’s a solid strategy,” Chief Mike Fisher told The Associated Press.

The new strategy draws on intelligence to identify repeat crossers and to try to determine why they keep coming, said Fisher, who was expected to address a House subcommittee on the plan Tuesday.

“This whole risk-based approach is trying to figure out who are these people? What risk do they pose from a national security standpoint? The more we know, the better informed we are about identifying the threat and potential risk,” he said in a recent interview.

Conditions on the border have changed dramatically since the last national strategy, putting pressure on the agency to adapt to a new landscape. An unprecedented hiring boom more than doubled the number of agents to 21,000 since 2004, accompanied by heavy spending on fencing, cameras, sensors and other gizmos.

At the same time, migration from Mexico has slowed significantly. Last year, the Border Patrol made 327,577 apprehensions on the Mexican border, down 80 percent from more than 1.6 million in 2000. It was the slowest year since 1971.

The Pew Hispanic Center reported last month that the largest wave of migrants from a single country in U.S. history had stopped increasing and may have reversed.

The new strategy moves to halt a revolving-door policy of sending migrants back to Mexico without any punishment.

The Border Patrol now feels it has enough of a handle to begin imposing more serious consequences on almost everyone it catches from Texas’ Rio Grande Valley to San Diego. In January, it expanded its “Consequence Delivery System” to the entire border, dividing border crossers into seven categories, ranging from first-time offenders to people with criminal records.

Punishments vary by region but there is a common thread: Simply turning people around after taking their fingerprints is the choice of last resort. Some, including children and the medically ill, will still get a free pass by being turned around at the nearest border crossing, but they will be few and far between.

The new strategy makes no mention of expanding fences and other physical barriers, a departure from the administration of President George W. Bush. Fisher said he would rule out more fences but, “It’s not going to be part of our mantra.”

The strategy makes only brief mention of technology in the wake of a failed $1 billion program that was supposed to put a network of cameras, ground sensors and radars along the entire border. Fisher said the agency is moving more toward mobile surveillance like unmanned aerial vehicles and helicopters.

“We’re still trying to understand what the capabilities are with all the technologies and the platforms,” Fisher said. “I’m just trying to figure out what is the best suite on all this stuff.”

The strategy makes it a top priority to ferret out corrupt agents, which has emerged as a growing threat as the agency has expanded.

It is the Border Patrol’s third national strategy since 1994, when the agency poured resources into the San Diego and El Paso, Texas, areas. That effort pushed migrants to remote mountains and deserts and made Arizona the nation’s busiest crossing for illegal crossings.

CINCINNATI (AP) — Police say a baby sitter for a one-year-old boy found dead in a Cincinnati apartment has been arrested on charges of abuse of a corpse and tampering with evidence.

Sgt. Gary Conner says Cincinnati police arrested 26-year-old Marquita Burch of Covington, Ky., on Saturday after she reported toddler William Cunningham missing Friday in Covington and then recanted her story. The child’s body was found in a closet of the Cincinnati apartment. Police don’t know how he died.

Burch is in jail in Cincinnati. Jail records list no attorney for her.

Police say Burch had been babysitting the toddler at an apartment complex in the northern Kentucky city.

Covington police received a call Friday that the child had wandered away from a playground and searched the area for five hours.

GLENWOOD, N.M. (AP) — Crews fighting a wildfire in the Gila National Forest in New Mexico benefited from lighter winds Sunday, allowing them to focus on building protection lines on key flanks of the blaze and preparing to send water-dropping helicopters into the air for the first time in several days.

The Whitewater-Baldy Complex fire continued to grow, burning more than 122,000 acres, or 191 square miles, by mid-day Sunday and was about two miles away from the privately owned ghost town of Mogollon in southwestern New Mexico.

SAN FRANCISCO (AP) — Crowds gathered along San Francisco’s waterfront Sunday, while San Francisco Bay was crowded with pleasure boats, tug boats and other vessels as the city celebrated the 75th anniversary of the Golden Gate Bridge.

Tens of thousands of people were expected to flock to the area to enjoy a number of events taking place along a section of waterfront stretching from Fort Point south of the bridge to Pier 39 along The Embarcadero.

At least several thousand people had gathered along the waterfront by Sunday afternoon, said Mary Currie, public affairs director for the Golden Gate Bridge, Highway and Transportation District.

WASHINGTON (AP) — A member of the National Labor Relations Board accused of leaking inside information has resigned.

The board says Republican Terence Flynn submitted his resignation Saturday. He had been under pressure to leave since March, when the board’s inspector general said Flynn committed ethics violations by improperly revealing confidential details on the status of pending cases.

Flynn shared the information with two former board members, including a one-time labor adviser to presidential hopeful Mitt Romney’s campaign. That adviser, Peter Schaumber, left the Romney campaign in December, around the time the investigation into Flynn began.

Flynn had denied any wrongdoing, but the inspector general issued a second report earlier this month finding even more improper disclosures. The allegations have been referred to the Justice Department.

WASHINGTON (AP) — The father of a U.S. soldier who was taken prisoner in Afghanistan is thanking the motorcycle riders of Rolling Thunder for raising awareness of missing-in-action troops and prisoners of war.

At the annual Rolling Thunder rally on the National Mall, Bob Bergdahl promised his son: “You will come home. We will not leave you behind.”

Army Sgt. Bowe Bergdahl, 26, of Hailey, Idaho, was taken prisoner in Afghanistan nearly three years ago. He is the subject of a proposed prisoner swap in which the Obama administration would allow the transfer of five Taliban prisoners long held at the U.S. military prison at Guantanamo Bay, Cuba.

Hundreds of thousands of bikers, including military veterans and non-veterans, gathered in the nation’s capital this weekend for the Rolling Thunder rally.
