U.S. officials used a forensic technique called vein analysis to corroborate the confession of Daniel Pearl’s self-professed killer, Khalid Sheikh Mohammed, who also is suspected of planning the 9/11 attacks on the United States; Mohammed was not part of the original plan to abduct Pearl; he told U.S. investigators that he was pulled in later by another senior al Qaeda operative; Mohammed was asked to take over because the kidnappers — midlevel and low-level Pakistani militants — did not know what to do with Pearl; Mohammed’s involvement presented al Qaeda with an opportunity for what it saw as a propaganda victory; a new report on Pearl’s assassination details problems in bringing to justice others suspected of involvement in the crime, including the recent release by Pakistan of a man thought to have been one of the main players

Mixtures of ammonium nitrate and fuel oil (ANFO) are used in about 80 percent of all explosives used in North America each year, mostly in the mining and demolition industries; they were also used by Timothy McVeigh in Oklahoma City, and in insurgents’ IEDs in Iraq and Afghanistan; explosives-grade ammonium nitrate can be refined from commercial-grade fertilizers using processes readily found online; there are even YouTube videos that break down the process step by step; commercial grade fertilizers are not regulated; those states that address the issue typically require merchants to keep records of who buys what, but there are no limitations on who can buy what and no reporting requirements

Intelligence and law enforcement authorities informed U.S. lawmakers that they are monitoring for potential “copycat” attacks on lawmakers after the rampage in Arizona on Saturday; Rep. Peter King, chairman of the House Homeland Security Committee, said he expects to ask for a formal report on the shooting, addressing both the short-term concerns — including the likelihood of copycat incidents — and long-term issues with security; among the questions he wants answered, King said, are “Is this part of a larger movement? Is there any evidence he [the assailant] was motivated by organizational structure?” FBI director Robert Mueller said: “Given this tragedy, all logical precautions are in place to best ensure the safety of other public officials, but there is no information at this time to suggest any specific threat remains”

The year which coming to an end saw several terror plots in the United States foiled; these plots had two things in common: They were launched by lone-wolf attackers, and the FBI was in the middle of them; experts say to expect more undercover cases in 2011, because the FBI has clearly decided that the best way to battle the growing threat of homegrown terrorism in this country is to confront the suspects directly
