A first-hand account of the situation, albeit a few weeks ago, by Peter Oborne and what better illustration of the lack of government:
..we visited a detention centre at Gharyan an hour’s drive south of Tripoli. The inmates were blacks, most of whom had been caught sneaking into Libya from sub-Saharan Africa in search of work. The thoughtful and engaging camp commander, a former English teacher called Emad Sagar...explained that he received no help of any kind from the government, that his militia fighters were untrained as prison guards, and that the only way he could feed the prisoners was by stealing from local businesses at gunpoint.

Elsewhere he wrote:
The government is offering payments of £10,00 to each fighter in an effort to persuade them to return to civilian life. It has reportedly already paid out around a billion pounds in this way, but that hasn't bought stability. At another roadblock, furious militiamen say they haven't been paid yet and vow to fight on.
