Sometimes drawing a diagram doesn't help:

Fox News Channel correspondent Geraldo Rivera is being expelled from Iraq for broadcasting details about future U.S. troop movements in the country, according to the Pentagon.
A primary obligation of the hundreds of reporters traveling with coalition forces in Iraq is to refrain from disclosing sensitive information about military operations.
The veteran correspondent, who was temporarily accompanying the Army's 101st Airborne Division, violated the rule during a live broadcast on Fox television. [...]
In the broadcast, Rivera instructed his photographer to tilt the camera down to the sand in front of his feet so that he could draw a map.
The Fox correspondent then outlined a map of Iraq, and showed the relative location of Baghdad and his location with the 101st Airborne unit.
Rivera then continued with his sandy diagram to illustrate where the 101st would be going next.
"He went down in the sand and drew where the forces are going," said a stunned senior military official. "He gave away the big picture stuff."
