If they were fair and objective, then, as a friend of mine suggested, some questions should be asked of them:
What body, institution or person will be investigating this suspected war crime?
The Palestinian Authority has been shown to be totally incapable of investigating itself so, perhaps the ICC is the appropriate venue for a trial. Moreover, maybe an NGO venue is appropriate or a framework like the Russell Tribunal?
Did the Arabs who murdered Livnat and wounded the others intentionally seek to kill innocent civilians?
Did they have evidence or any reason to think that they were firing their weapons at a legitimate military target rather than civilians?
Was disproportionate forced used?
What is the responsibility of political and military personnel in this?
Does a policy of targeting civilians exist?
What is the responsibility of the states and individuals involved in providing the weapons and training? Is the United States a body to be investigated?
Should the Oslo Accords be renegotiated in this matter of religious sites?
