Officials in Benghazi said that the first problem with pursuing those responsible for the attacks is that police officers here are afraid to move against the Islamist extremist suspects, who, like many in this country, are members of militias that are better armed than state security forces.

And that is just the beginning. Officials say it’s uncertain who is in charge of investigating the case and who has the authority to issue arrest warrants, should it come to that. Even if charges were to be brought, there is no proper court system for prosecuting anyone.

In Benghazi, the deputy interior minister said the prosecutor is in charge. The head of the Supreme Security Council, which has responsibility for organizing an army, believes the police are in charge. The prosecutor said he has no idea who is in charge. Some brigades created during last year’s uprising and used to filling the security void here don’t recognize the Tripoli authorities as in charge of matters in Benghazi.
