Zach Beauchamp argues that the attempted murder of a group of Arabs by a larger group of Jewish teenagers in Jerusalem cannot be understood without understanding the growing violence of some settlers:

These incidents fit into a disturbing pattern of growing violence committed by radical Israelis, particularly in the West Bank. Last December, Defense Minister Ehud Barak warned about "homegrown terror" attacks committed by extremist settlers against Israeli soldiers and Palestinian civilians. There had been an uptick in "price tag" attacks, referred to as such because the terrorists were intending to exact a price for any moves by the Israeli government towards dismantling illegal settlements or withdrawing from the West Bank.

A new report written by two experts on Israeli counterterrorism at the Brookings Institute, Daniel Byman and Natan Sachs, suggests that the problem may be more serious than some had previously thought. Byman and Sachs, citing UN numbers, find that the number of "price tag" attacks had roughly doubled from 2009 to 2011 with limited response from Israeli authorities: over 90 percent of investigations into incidents of settler violence over the past ten years ended without indictments. The attacks have escalated recently, Byman and Sachs argue, as a consequence of the rise of an extremist subculture among young, religious settlers:
[O]ver the last several years, the evolution of the settler community has also led to the growth of a small but significant fringe of young extremists, known as the "hilltop youth," who show little, if any, deference to the Israeli government or even to the settler leadership. No matter how strongly Gush Emunim opposed government policy, it always officially avoided vigilante violence. But these young radicals, who largely live in settlements deep in the West Bank and do not affiliate with traditional religious authorities, have embraced it. These settlers -- likely no more than a couple thousand, a small but dangerous minority within the broader community -- are the ones leading the "price tag" attacks against Palestinian civilians and Israeli soldiers. They have lost faith in the notion that the state, under its current leadership, is key to settling the Land of Israel. Instead, they see it as an obstacle to God's will.
