On Monday's broadcast of CNN's "Situation Room," Sen. Chris Murphy (D-CT) stated that Hamas has been using civilians as human shields from the start and "to the extent that there are very high numbers of civilian casualties, the primary responsibility for that lies with Hamas," but "the number of civilians dying, it has a moral cost, but it also has a long-term strategic cost to Israel." And Israel should "place a high, maybe higher level of importance on the number of civilians that are affected by these operations."
