Natan-Zada was born to an Israeli-Jewish family that had immigrated to Israel from Iran and Yemen. Natan-Zada's parents describe him as having been a "bright and studious Israeli schoolboy" prior to his becoming involved with the Jewish extremist Kahanism movement, to which he was introduced via the Internet. He then began spending weekends in Kfar Tapuach, an Orthodox West Bank settlement. During his national service in the Israel Defense Forces (IDF), Natan-Zada deserted the army and hid in Kfar Tapuach to avoid further service.
The Israel Police opened a criminal investigation into Zada's lynching.  The High Follow-Up Committee for Arab Citizens of Israel called on the government to refrain from investigating the death of Eden Natan-Zada. Arab Knesset member Mohammad Barakeh, a Shefa-'Amr resident himself, warned that protests could erupt if police probe Zada's lynching: "Normally when someone stops a terrorist from continuing to kill he is considered a hero, but in this case it is the heroes who are sitting on the defense stand". However, Shefa-'Amr's security officer, Jamal Aliam, told Army Radio that Zada had been attacked by dozens of people after he had been handcuffed and subdued by police.  Eventually, on 13 June 2006, five suspects in the lynching were arrested, one who was already serving a prison sentence was brought in for questioning, and a seventh suspect turned himself in after learning he was wanted by police. The police said: "We're responsible for maintaining the law, and you can't take the law into your own hands even when it concerns a terrorist who murdered innocent people, even though he made a heinous terrorist act". Two suspects were subsequently released. There was general support for their arrest and even left-wing activist Yossi Beilin said: "Israel can't put up with a lynch made on a handcuffed person even if his actions are heinous and unforgivable. It's a combined interest of both Jews and Arabs that Israel won't close its eyes to such behaviour". The Arab Knesset members however demanded their release and called their arrest a crime.  On 7 June 2009, twelve Arab citizens were indicted over the lynching in the Haifa District Court. Seven were charged with attempted murder. In March 2010, Maher Talhami, their defense lawyer, stated that recently discovered aerial footage of the bus, recorded by an Israeli drone before, during and after the attack took place indicates that Israeli defense officials were aware of Natan-Zada's intentions.  In July 2013, the seven defendants charged with attempted murder were acquitted of that charge, but four were convicted of attempted manslaughter and two were convicted of aggravated battery, while one was exonerated entirely. The sentencing took place on 28 November 2013. Three were sentenced to two years in prison, while one was sentenced to 20 months, one to 18 months, and one to 11 months.

Why were they released?

Answer the question at the end by quoting:

Thomas Sowell (; born June 30, 1930) is an American economist, social theorist, political philosopher, and author. He is currently Senior Fellow at the Hoover Institution, Stanford University. Sowell was born in North Carolina, but grew up in Harlem, New York.
Sowell has also written a trilogy of books on ideologies and political positions, including A Conflict of Visions, where he speaks about the origins of political strife; The Vision of the Anointed, where he compares the conservative/libertarian and liberal/progressive worldviews; and The Quest for Cosmic Justice, where, as in many of his other writings, he outlines his thesis of the need for intellectuals, politicians and leaders to fix and perfect the world in utopian, and ultimately he posits, disastrous fashions. Separate from the trilogy, but also in discussion of the subject, he wrote Intellectuals and Society, where, building on his earlier work, he discusses what he argues to be the blind hubris and follies of intellectuals in a variety of areas.  Sowell challenges the notion that black progress is due to progressive government programs or policies, in The Economics and Politics of Race, (1983), Ethnic America (1981), Affirmative Action Around the World (2004), and other books. He claims that many problems identified with blacks in modern society are not unique, either in terms of American ethnic groups, or in terms of a rural proletariat struggling with disruption as it became urbanized, as discussed in his book Black Rednecks and White Liberals (2005).  In Affirmative Action Around the World Sowell holds that affirmative action covers most of the American population, particularly women, and has long since ceased to favor blacks.  Sowell described his serious study of Karl Marx in his autobiography. He opposes Marxism, providing a critique in his book Marxism: Philosophy and Economics (2011).  Sowell also favors decriminalization of all drugs.
