sounds like the 517th hearing has finally got a little meat.
first, given the intelligence, more protection should have been in place at the benghazi location.
second, the response to the attack was slow.
third, two government departments tried to avoid responsibility for the mess and influenced some talking points until they were reduced to saying nothing but "mummy, orange, yum yum."
these are not good things.
but given the us has only one set of lawmakers, perhaps a fourth point should be made.
us congress has no sense of relative importance. how about worrying about cancer? or fatal accidents? or drone attacks? or syria? or afghanistan? or ...?
embassy attacks happen with a low but inevitable frequency. you want to invest in protection? then get taxes raised to pay for it.
