According to the Hurriyet Daily News:
Security cameras were not recording at the moment of the blast due to a power outage in the area, according to claims. It is not clear whether or not the embassy building was the only building experiencing the outage, Hürriyet reported on its website. Officials from the company that is responsible for the the capital’s power are reportedly at the scene as well.
It is surprising–and a significant vulnerability–that security cameras would be dependent upon the local power supply, rather than an independent source. Benghazi revealed serious flaws which had developed in embassy and consulate security during the past four years and perhaps before. It seems, however, that Benghazi exposed only some of the complacency which has developed.
It is fortunate that no Americans were killed in the attack–although two Turkish security guards were reportedly killed and a Turkish journalist wounded. That we got relatively lucky, however, should not stop senators from asking what good are security cameras when they are only as reliable as local power and when terrorists could very easily cut the lines.
