Well, just a few:
2001 anthrax attacks. A March 2004 State Department report on "Significant Terrorist Incidents, 1961-2003" quotes then-Attorney General John Ashcroft saying of the letters containing anthrax mailed to various targets: "When people send anthrax through the mail to hurt people and invoke terror, it's a terrorist act." Five people were killed as a result of those letters in the autumn of 2001.
2001 shoe bomber attempted attack. In June 2008, then-Homeland Security Secretary Michael Chertoff described Reid's December 2001 attempt "to blow up a trans-Atlantic plane with a shoe bomb" as an attempt to "carry out terrorist operations for Al-Qaeda."
2002 attack against El Al ticket counter at LAX. In July 2002, Hesham Mohamed Hadayet opened fire at an El Al Airlines ticket counter at Los Angeles International Airport killing two people and wounding four others before being shot dead. A 2004 Justice Department report stated that Hadayet's case had been "officially designated as an act of international terrorism."
2002 DC-area sniper. The state of Virginia indicted Washington, D.C.-area sniper John Allen Muhammad -- along with his accomplice, a minor at the time -- on "an act of terrorism" for one of the murders he committed during a three-week shooting spree across Maryland, Virginia, and Washington, D.C. Muhammad was convicted, sentenced to death, and subsequently executed for the crime.
2006 UNC SUV attack. In March 2006, University of North Carolina-Chapel Hill graduate Mohammed Reza Taheri-azar drove an SUV into an area of campus, striking nine pedestrians. According to reports, Taheri-azar said he acted because he wanted to "avenge the deaths or murders of Muslims around the world." Taheri-azar also reportedly stated in a letter: "I was aiming to follow in the footsteps of one of my role models, Mohammad Atta, one of the 9/11/01 hijackers, who obtained a doctorate degree."

Lucas John Helder (born May 5, 1981) was a University of Wisconsin–Stout college student and Pine Island, Minnesota, resident who earned notoriety as the Midwest Pipe Bomber in May 2002.
Helder's plan was to plant pipe bombs in mailboxes across the United States to create a smiley face shape on the United States map. The bombs, which were packed with BBs and nails, were rigged to explode as the mailboxes were opened. Completed and rigged bombs were found in Nebraska, Colorado, Texas, Illinois and Iowa. In Iowa, six people, including four mail carriers, were injured when the bombs detonated. Ultimately, Helder planted 18 bombs and covered 3,200 miles. He was eventually captured in rural Nevada before he managed to complete the full smile. At the time of his arrest, police were looking for an unknown suspect driving around in a black Honda Accord and newspapers reported that he was wearing a Kurt Cobain T-Shirt. The bombings were heavily covered by the United States media.
http://en.wikipedia.org/wiki/Luke_HelderThe 2005 University of Oklahoma bombing occurred on October 1, 2005 at approximately 7:30 p.m. CDT, when a bomb went off near the George Lynn Cross Hall on Van Vleet Oval on the University of Oklahoma (OU) main campus. The blast took place less than 200 yards west of Oklahoma Memorial Stadium, where 84,501 spectators were attending a football game. The bomber, OU student Joel "Joe" Henry Hinrichs III, was killed in the explosion; no one else was killed.
After the incident, speculation began immediately about Hinrichs' motivation and the number of accomplices, if any. An off-duty police officer noted a discussion Hinrichs had with a local feed store owner about ammonium nitrate and had begun an investigation, one heightened by innuendo regarding the Pakistani heritage of the bomber's roommate. Terrorism-related speculation further erupted when the explosive agent was found to be TATP, the compound used in the July 2005 London bombings, as well as in an infamous attempt to destroy a transatlantic flight by igniting a shoe and by Hamas in clandestine devices intended for detonation by suicide bombers. The Federal Bureau of Investigation (FBI) and local authorities concluded in 2006 that Hinrichs was alone and had no assistance from terrorist groups, but could not prove or disprove allegations that Hinrichs intended to enter the packed stadium and kill football fans along with himself.

Naveed Haq has been accused of conducting the shooting, and is currently standing trial. Police have classified the shooting as a "hate crime" based on what Haq is alleged to have said during a 9-1-1 call. King County Prosecuting Attorney Norm Maleng described the shooting as "one of the most serious crimes that has ever occurred in this city".
