Why do some radical people turn to violence while others do not? Experts say that we really do not know for sure, but we need to know if we want to strengthen our counter-terrorism measures; until the understanding of this improves, the efforts to stop further terrorist attacks will continue to rely on a lot of luck

Two weeks after the 7 July attacks, the then prime minister, Tony Blair, called a press conference at which he warned: “Let no one be in doubt. The rules of the game have changed”; he outlined twelve new measures that aimed to transform the landscape of British counterterrorism; together, they were intended to offer a greater degree of collective security; each came at considerable cost to the liberties of both individuals and groups of people; the controversial Terrorism Act 2006 passed after the 7 July bombings has led to increased arrests and convictions

Terrorists see public surface transportation as a killing field; despite their continuing obsession with attacking commercial aviation, when it comes to wholesale killing, trains and buses offer easily accessible concentrations of people

The administration planned to invest $70 million in building one of the U.S. largest anti-terrorism training center near the town of Ruthsburg on Maryland’s East Shore; stiff opposition from local residents, environmentalists, and Republican in Congress convinced the General Services Administration to scrap the plan

The Canadian Association of Agri-Retailers wants a comprehensive plan of action to prevent agricultural supplies such as fertilizers from becoming tools of terrorists; the association calls for an “integrated crop input security protocol” for Canada’s 1,500 agri-retail sites; this plan would include perimeter fencing, surveillance and alarm devices, lighting, locks, software, and staff training in various security techniques, at retail outlets; estimated cost: $100 million

North Carolina universities and state and federal agencies create the new North Carolina Bio-Preparedness Collaborative; the idea is to use computers to link all the disparate forms of data collected by various agencies quickly to root out indicators of new disease, or food-borne illness, or, in a worst-case scenario, an attack of bio-terrorism

Bill calls for bolstering U.S. defenses against future bioterror attacks requiring the director of national intelligence to produce and administer a National Intelligence Strategy for Countering the Threat from WMD, which would be created in consultation with the homeland security secretary as well as other relevant agencies

Faisal Shahzad, a U.S. citizen born in Pakistan, said in court Monday that his failed car bomb plot was backed and financed by the Pakistan Taliban; the group, though, is not yet labeled a terrorist organization by the U.S. government, unlike al Qaeda and its affiliates; lawmakers want to change that

Many terrorist organizations also provide basic services such as education, health, and welfare to the people they say they represent; since the corrupt and ineffective central governments do not provide such services, militant organizations step in to fill the void; those who send money to these organizations or provide other help argue that they aim to support the humanitarian activities of the these organizations, not their terror campaigns; the U.S. Supreme Court says this is a distinction without a difference; there is also no violation of the First Amendment here: “independently advocating for a cause is different from the prohibited act of providing a service to a foreign terrorist organization,” the Court ruled
