In the police training simulation called "Hogan's Alley," officers are presented with a series of human-shaped targets that pop up in doors, windows, and so on in an alley in a tough neighborhood. They must not fire on innocent bystanders--- the "don't shoot" targets--- but failure to shoot at an armed criminal is equally deadly, both to the officer and to innocent people. The bad guy, or "shoot" targets, always display some kind of deadly weapon plus criminal intent. Now that you understand "Hogan's Alley,"
Let's play "Pallie Alley"

You are an Israeli soldier or an armed Israeli civilian, and you are presented with the targets shown at right. You must make a split-second decision to shoot or not shoot. A wrong decision (either way) will cost innocent lives. Is he a father with a baby, or is he a suicide bomber with a doll's head on his package of explosives? He's walking into a pizza parlor, bus, or Passover Seder; you have about a second to make up your mind. Is this Palestinian businessman looking at his watch to see if he's on time for his appointment with his client as he walks into an Israeli office building, or is this terrorist checking to see when the bomb in his briefcase will explode? Is this ambulance carrying medical personnel and patients, or explosives?* A house of worship or a gun emplacement?

What's the matter? You don't like this game because you can't tell the "shoot" targets from the "don't-shoot" targets? Guess what: Israel doesn't like it either, but it's the Palestinians who choose to play it this way.

* A Palestinian ambulance driver was in fact caught transporting explosives, thus abusing the Red Crescent (Muslim equivalent of the Red Cross).
