We are lead to believe that there is a moral difference between bombing an abandoned hospital that snipers took cover in and bombing a hospital that you ordered to be evacuated before the snipers took cover.
Unfortunately, the end result is the same, Gaza looses a hospital.
A similar tactic was used today to destroy a UN run school sheltering displaced families seeking shelter from the onslaught. Unfortunately not enough time was allowed for the evacuation and as men, women and children (families) waited in the courtyard for evacuation the Israeli bombs started falling killing over a dozen people and wounding an undisclosed number.
That should teach the UN, to suggest that Israel might be guilty of war crimes for not taking enough care to avoid killing innocent civilians (families).
