Candidate passages:
The City of San Francisco has sometimes grappled with what to do about camps of homeless people living in Golden Gate Park, which have been criticized as unsanitary, and "demoralizing" for park users and workers.
The camps have been described by journalists as full of garbage, broken glass, hypodermic needles, and human excrement, and the people in them are described as suffering from serious addictions and often behaving aggressively with police and park gardeners.
There have been occasional incidents of violence against homeless people in the park, including the 2010 park beating to death of a homeless man and an attack on park visitors by dogs owned by a park resident, also in 2010.
In the 1990s, then-Mayor Willie Brown sought unsuccessfully to borrow the Oakland Police Department's helicopters in order to find homeless people's camps.
Starting in 1988 under then-mayor Art Agnos, and continuing under the direction of subsequent mayors including Frank Jordan, Willie Brown, and Gavin Newsom, San Francisco police have conducted intermittent sweeps of the park aimed at eliminating the camps.
Tactics have included information campaigns designed to inform homeless residents about city services available to help them; waking sleeping homeless people and making them leave the park; issuing citations for infractions and misdemeanors such as camping, trespassing, or public intoxication, which carry penalties of $75 to $100; and the seizure and removal from the park of homeless people's possessions.
The crackdowns have been criticized by anti-poverty activists and civil liberties groups, who say they attack only the symptoms of homelessness while ignoring its root causes, and criminalize the poor for their poverty while ignoring their property rights and constitutional rights.
In 2006, the American Civil Liberties Union brought a lawsuit against the city government on behalf of 10 homeless people, alleging property violations by the city during sweeps in Golden Gate Park the year before.

Prime Minister Silvio Berlusconi caused a controversy when he said, in an interview to the German station n-tv, that the homeless victims should consider themselves to be on a "camping weekend" - "They have everything they need, they have medical care, hot food... Of course, their current lodgings are a bit temporary.
But they should see it like a weekend of camping."
To clarify his thought, he also told the people in a homeless camp: "Head to the beach.
It's Easter.
Take a break.
We're paying for it, you'll be well looked after."
The billionaire prime minister offered his own houses to some of the survivors.

Even as the nationalist camp and socialist camps sought mutual cooperation, the socialists looked beyond the strict class ideology that marked the earlier movement, and from 1924 could be categorized into two camps: the cooperative nationalist camp and the revolutionary nationalist camp.
As a result, from 1926, there started to be an organizational start to this search for an uncompromising movement.
Although they were not successful in actualizing these plans, Kang Talyǒng, who was the second secretariat of the Korean Communist Party, made contact with Kwǒn Tongjin, An Chaehong, and Kim Chunyǒn, among others.
The Korean National Party’s desire to create an organized national front in response to the general trend towards the Autonomy Movement is a representative example of the situation at the time.
The cooperation between recalcitrant nationalists and socialists progressed rapidly as the Chǒng’uhoe (正友會) published the Chǒng’uhoe Statement which advocated the establishment of a singular nationalist body that was a coalition between nationalist and socialist camps.
