A street is a paved public thoroughfare in a built environment. It is a public parcel of land adjoining buildings in an urban context, on which people may freely assemble, interact, and move about. A street can be as simple as a level patch of dirt, but is more often paved with a hard, durable surface such as concrete, cobblestone or brick. Portions may also be smoothed with asphalt, embedded with rails, or otherwise prepared to accommodate non-pedestrian traffic.

Originally the word "street" simply meant a paved road (Latin: "via strata"). The word "street" is still sometimes used colloquially as a synonym for "road", for example in connection with the ancient Watling Street, but city residents and urban planners draw a crucial modern distinction: a road's main function is transportation, while streets facilitate public interaction. Examples of streets include pedestrian streets, alleys, and city-centre streets too crowded for road vehicles to pass. Conversely, highways and motorways are types of roads, but few would refer to them as streets.

Nidal Malik Hasan, USA (Arabic: نضال مالك حسن‎; born September 8, 1970) is a United States Army officer and sole accused in the November 5, 2009, Fort Hood shooting, which occurred less than a month before he would have deployed to Afghanistan.

Born in Virginia to parents who moved to the United States from a Palestinian town near Jerusalem, Hasan joined the Army while in college and became a psychiatrist at Fort Hood, Texas. Prior to the shooting, Hasan had expressed extremist views which had been brought to the attention of his superiors and the F.B.I.. Hasan was discovered to have exchanged emails with Imam Anwar al-Awlaki asking for spiritual guidance regarding violence. Al-Awlaki has since been linked to other attacks by radical Muslims, and he quickly blessed the Fort Hood operation because it was against a military target. Al-Qaeda spokesman Adam Gadahn also praised the "Mujahid brother" as a "pioneer, a trailblazer and a role-model." The attack was described by a Senate report as "the worst terrorist attack on U.S. soil since September 11, 2001." General Jack Keane testified before a Senate committee that his first reaction was "...just how unacceptable the military’s failure to deal properly with Major Hasan’s radicalization to violent Islamist extremism was." He also agreed with "...the report’s conclusion that Hasan’s open displays of violent Islamist extremism was (sic) a violation of military rules calling for good order and discipline." He listed what he believed to be "...some of the obvious signs that Hasan should have been discharged..."
