PHYLLIS BENNIS – France is in mourning and in shock. We still donâ€™t know how many people were killed and injured. In fact, thereâ€™s a lot we still donâ€™t knowâ€”including who was responsible. The ISIS claim of responsibility tells us virtually nothing about who really planned or carried out the attacks; opportunist claims are an old story. But the lack of information hasnâ€™t prevented lots of assumptions about who is â€œobviouslyâ€ responsible and what should be done to them. Already the call is rising across Franceâ€”â€œthis time itâ€™s all-out war. But we do know what happens when cries of war and vengeance drown out all other voices; weâ€™ve heard them before.
