The raid in Los Angeles came after demonstrators with the movement in Philadelphia marched through the streets after being evicted from their site. About 40 protesters were arrested after refusing to clear a street several blocks northeast of City Hall, Philadelphia Police Commissioner Charles Ramsey. They were lined up in cuffs and loaded on to buses by officers. Six others were arrested earlier after remaining on a street police that police tried to clear.

Los Angeles Mayor Antonio Villaraigosa raised public safety and health concerns in announcing plans for the eviction last week, while Philadelphia officials said protesters must clear their site to make room for a $50 million renovation project.

Defiant Los Angeles campers who were chanting slogans as the officers surrounded the park, booed when an unlawful assembly was declared, paving the way for officers to begin arresting those who didn’t leave.

In the first moments of the raid, officers tore down a tent and tackled a tattooed man with a camera on City Hall steps and wrestled him to the ground. Someone yelled “police brutality.”

Teams of four or five officers moved through the crowd making arrests one at a time, cuffing the hands of protesters with white plastic zip-ties. A circle of protesters sat with arms locked, many looking calm and smiling.

Opamago Cascini, 29, said the night had been a blast and he was willing to get arrested.

“It’s easy to talk the talk, but you gotta walk the walk,” Cascini said.

At least two dozen people had been arrested in the first two hours and police said they planned to arrest the 75 people remaining in the park. Police Cmdr. Andrew Smith said one person was arrested for violence against a police officer, but Smith couldn’t provide details.

Police used a cherry picker to pluck five men from trees. Two others were in a tree house — one wore a crown and another taunted police with an American flag.

In Philadelphia, police began pulling down tents at about 1:20 a.m. EST after giving demonstrators three warnings that they would have to leave, which nearly all of the protestors followed. Dozens of demonstrators then began marching through the streets and continued through the night.

Ramsey said breaking up the camp in the early-morning hours helped minimize any disruption to businesses and traffic.

“We acknowledge the fact that we are going to have to leave this space …. but in another sense this has been our home for almost two months and no one wants to see their home taken away from them,” Philadelphia protestor Bri Barton, 22, said before police began clearing out the camp.

“Whether or not we have this space or work in the city is nowhere near done,” she said.

The eviction overall appeared to have been carried out without any significant scuffles or violence.

Demonstrators and city officials in both Los Angeles and Philadelphia were hoping any confrontation would be nonviolent, unlike evictions at similar camps around the country that sometimes involved pepper spray and tear gas. The movement against economic disparity and perceived corporate greed began with Occupy Wall Street in Manhattan two months ago.

About 1,200 Los Angeles officers staged for hours outside Dodger Stadium before the raid. They were warned that demonstrators might throw everything from concrete and gravel to human feces at them.

“Please put your face masks down and watch each other’s back,” a supervisor told them. “Now go to work.”

Before police arrived in large numbers, protesters were upbeat and the mood was almost festive. A protester in a Santa Claus hat danced in the street. A woman showed off the reindeer antlers she had mounted on her gas mask.

Some were smoking pot, some were carrying gas masks, others wore hoodies and had bandanas around their faces. Some protesters carried lit candles and held signs saying “Defend Occupy LA.”

Fireworks exploded in the sky at one point. Later, as helicopters hovered above, someone blew “The Star Spangled Banner” on a horn.

As officers first surrounded the camp, hundreds of protesters chanted, “The people united will never be defeated.”

Campers planning to defend the camp and hold their ground barricaded entrances to the park with trash cans.

The police operation was planned at night because downtown is mostly vacant, with offices closed, fewer pedestrians and less traffic, but a spokesman said it could make officers more vulnerable.

“It’s more difficult for us to see things, to see booby traps,” Lt. Andy Neiman, told pool reporters. “Operating in the dark is never an advantage.”

Neiman said the force was prepared to deal with demonstrators holed up in the camp or those who had climbed up trees in the small park.

Gia Trimble, member of the Occupy LA media team, said a lot of people committed to the cause would stay and risk arrest.

“This is a monumental night for Los Angeles,” Trimble said. “We’re going to do what we can to protect the camp.”

In their anticipation of an eviction, the Los Angeles protesters designated medics designated with red crosses taped on clothing. Some protesters had gas masks.

Organizers at the camp packed up computer and technical equipment from the media tent.

Two men who constructed an elaborate tree house lashed bamboo sticks together with twine to push away any ladder police might use to evict them.

Police said they would be able to remove the tree climbers.

Members of the National Lawyers guild had legal observers on hand for an eviction.

“I think she was smart enough and planned ahead and prepared to not be in this type of situation,” she said, visibly shaken and holding back tears.

The Adams had been sailing full-time on their 58-foot yacht, the Quest, since December 2004 after retiring. They often travelled with friends, and on this trip were joined by Riggle and Macay.

Mariners were warned about traveling around the Horn of Africa because of the risk of pirate attacks. The four sailors traveled with a large flotilla to stay safe earlier in the trip, but left the group at the time of the attack, said Crossland.

The pirates shot the four after firing a rocket-propelled grenade at a U.S. warship, one of several vessels tracking the hijacked boat over the weekend. Fifteen men were captured.

Macay, 59, was wounded but alive when Navy SEALs boarded the Quest after the shooting, but she died later, her niece said.

Macay and Riggle had left Seattle on Riggle’s sailboat for a world voyage in September 2007, but in recent years had been crewing on separate boats, said Macay’s friend Cynthia Kirkham, of Seattle.

Joe Grande, a fellow member of the Seattle Singles Yacht Club, said the deaths were like losing family to those who knew the pair.

“Great sailors, good people. They were doing what they wanted to do, but that’s small comfort in the face of this,” Grande said.

The U.S. flag flew at half-staff Tuesday at the Del Rey Yacht Club in Marina del Rey, a small boat harbor on the Southern California coast where the Adams made their base.

Gary Deitsch, commodore of the club, said members were devastated by the killings. The couple had belonged to the club since 2001.

“We are deeply saddened,” he said. “We hope their deaths will bring about the world’s focus to eliminate this violence.”

DeDe Allen, the club’s secretary who was a friend of couple and had sailed with them, said they were last in Marina del Rey in December.

“They were just wonderful people to be with,” Allen said. “Their personal mission was enjoying life.”

Scott Adam, who was in his mid-60s, had been an associate producer in Hollywood when he became spiritual and enrolled in Fuller Theological Seminary in Pasadena a decade ago, said Robert K. Johnston, a professor at the seminary.

His wife had been a dentist, Torgerson said.

At St. Monica’s Catholic Church in Santa Monica, where the Adams were parishioners and Jean Adam sang in the choir, Monsignor Lloyd Torgerson described the killings as heartbreaking during morning Mass.

The Adams took Bibles with them to distribute to far-flung corners of the world, he said.

“They were an extraordinary couple,” Torgerson said. “They were joyful people.”

Riggle was a relief veterinarian for the Seattle Animal Shelter for the past eight years or so, spaying and neutering adopted animals, said director Don Jordan.

“He wasn’t a man of many words, but he was a kind-hearted individual with a great passion for animals and animal welfare,” Jordan said.

Riggle once took a colleague’s family sailing when their daughter was diagnosed with cancer to get their mind off their troubles. “That was just a small indicator about how he treated people,” he said.

Macay was vice president for training and development for Profitability Consulting Group, an adviser to retail furniture stores based in Hillsborough, N.C. She and Riggle were romantically involved when they first met, but later were friends who sailed together, Kirkham said.

Profitability Consulting CEO John Eggers said Macay was regarded in the industry as one of the top educators and presenters on design and sales.

“She was such a free spirit,” Eggers said. “She was just a real professional and just loved life.”

City attorney’s office spokeswoman Cindy Shin said the office has not had a chance to fully review the decision and had no immediate comment.

The class-action lawsuit was filed in 2009, spurred by events during Hurricanes Katrina and Rita in New Orleans, when many disabled people were abandoned and left stranded during evacuations because of a lack of disability planning.

Advocates for disabled people said they hoped the ruling in Los Angeles would cause other cities to examine disaster preparedness policies.

“This is society’s moral duty to people with disabilities,” said Lilibeth Navarro, executive director of Communities Actively Living Independent and Free.

The lawsuit noted that Los Angeles is particularly vulnerable to disasters, including earthquakes, wildfires and possibly terrorist attacks. The city has some 800,000 disabled residents out of a population of about 4 million, according to the Disability Rights Legal Center in Los Angeles.

A disability disaster plan would include provisions for transportation and evacuation assistance, and wheelchair-accessible emergency shelters equipped with electricity for people on life-saving machines, refrigeration for medicines, and commonly used medications, said Shawna L. Parks, director of the disability rights center.

“These will be life and death issues for thousands of people with disabilities in the event of a major disaster,” she said.
