American Corporations tied to Libya

Silence from the White House on Libyan military's killing of 300+ unarmed protesters. Could the fact that Chevron, Raytheon, Shell, Halliburton, General Dynamics, & Dow Chemical are all members of the US/Libya Business Association have something to do with it? Could it be General Dynamic's $165 Million contract to arm the Libyan military? Gotta love corporate America.
