A sightline, sight line or visual axis, is a normally unobstructed line-of-sight between an intended observer (or spectator) and a stage, arena, or monument, for example. Sightlines are a particularly important consideration in theatre and stadium design, road junction layout and urban planning. sightline, sight line or visual axis, is a normally unobstructed line-of-sight between an intended observer (or spectator) and a stage, arena, or monument, for example.

The CIA does do undercover (spy like) procedures because sometimes it has to but in actuality most of its information comes from people who offer to supply information. These people provide support to the CIA in support of their ideological, religious, political and personal beliefs. Some for vengence and others just out of greed.
While movies romanticize spies, it is the CIA analyst's job to interpret the information collected by agents in the field, determine what may or may not be useful information and deliver their findings to the Directorate of Intelligence in order to help to make America's interests safer at home and abroad.
