....and you have nothing in response. They lied about not knowing whether Hamas police were civilian or combatant.
You also mentioned International Law but never pointed to that exact law. ICRC interpretations are not international law. Their experts couldn't even come to a majority opinion on defining civilians. So you really have no idea what you're talking about & B'tselem lied again when they presented a non-majority expert opinion from the ICRC as well-defined International Law.
Besides, civilians are not combatants. Presumably, Osama bin Laden - a combatant and in no way a civilian - could fire a rocket at Israel in plain clothes, run off in some direction without a weapon, and get killed by Israel a few minutes later. You believe Bin Laden should then be counted as a civilian under IHL. That's absurd and not what the ICRC is talking about. OBL is a combatant, considered uniformed army and not a civilian. If you as an ordinary civilian wanted to spontaneously help OBL in some way (hide Osama in your home or let him fire a rocket at Israel from your backyard) that's another story altogether. That's when the ICRC definitions of civilians come in.
Get it now?
Hamas and Islamic Jihad terrorists are de-facto militants at the time they're killed, not civilians. Whether they dress as military or try to hide in civilian clothing. They're considered uniformed army, not civilians. They're not protected like civilians.
Consider yourself refuted. Utterly.
I also don't expect to see you using discredited, dishonest lying sources such as B'tselem anymore.
