No one at any level in the CIA told anybody not to help those in need; claims to the contrary are simply inaccurate.In other words, the decision not to assist came from either State, Defense, or the White House. Panetta at Defense has waffled, said intel was insufficient to act, so has Clinton at State.
True, intel was insufficient to know who was causing the trouble. However, intel that there was trouble and our people were in danger was clear and unambiguous.
What remains to be determined is who decided to do nothing and let those four people be murdered. Clinton has taken responsibility, sort of.
If it's her responsibility she should, at minimum, resign now, perhaps be tried. She has announced she will step down in January, regardless of who is elected president.
