Main Example
Is Osama bin Laden still actively leading al Qaeda? Unlikely, says President Musharraf. The latter recently told NBC that, thanks to intense surveillance by the U.S. and Pakistani military, "Osama's physical movements as well as his use of telecommunication devices" are so circumscribed that he can no longer effectively steer that terrorist network.
Workplace Examples

Other Examples
