This will explain you why the B'Tselem's registration of a case where a Palestinian is hurt by Israel, does not infringe the rights of an Israeli victim from Palestinian hand, unregistered by the same HRO. Israeli Jews do not constitute an "other side" for Israeli Arabs since there might be Israeli Ethiopians protesting their illegal treatment without any regard of their views on the Israeli Arabs, Jews or Russians. They are all subjects of law and it is precisely creating pairs of oppositions? for a "balanced image" that would infringe the rights of those numerous parties who don't appear in the opposition. Take ADL (even if it is more of an interest group than a HRO). A bit paradoxically they cover sometimes non-Jewish cases but they heavily focus on Jewish/Israeli ones and will never claim they take legal responsibility for drawing the "balanced image" on defamation cases in the world.
