There has been a corresponding change of tactics by those manning checkpoints. 3 drivers have been shot trying similar things since then. ABC Radio news this morning.
As we should use Israeli tactics in urban fighting we should also use Israeli rules of engagement at checkpoints. Any out-of-line behavior is dealt immediately with lethal force. More taxi drivers have been shot to death at Israeli checkpoints then any other people (when they have tried to avade or run the checkpoints, typically) because the IDF knows taxis are often used as a mask for suicide bombers.
Here is another case where if we just allowed the IDF to fight with us, the Brits and the Aussies, there would be fewer U.S. casualities. We have no closer ally in the world, yet no army we keep more at arm's length to satify Jew-hating Arab dictatorships. I cannot understand this.
