The Palestinian knack of innovation, totally lacking when it comes to positive things such a nation building, society building, or generally creating a better lives for themselves, can always be relied upon to find new ways of killing Israelis. Hamas has praised the act, though it's hard to see how it in any way does anything good for any Palestinian interest conceivable. But then again, since when has Hamas been interested in Palestinian interests as defined in any recognizable rational way?
Meanwhile, another group that can always be relied upon are the folks at the Guardian. I can't link to their front page since it changes every few hours, so you'll have to believe me that their headline about the attack, as posted on their homepage, says "Bulldozer driver shot after rampage in Jerusalem". When you click on the link you get to this article, which has a headline only marginally less offensive: "Man shot dead after Jerusalem bulldozer rampage". That's right. You've got to keep your priorities straight. Those Jerusalemites, they're mighty easy with their firearms, you know, and all it takes is for a bulldozer driver to do a little rampaging, sort of like what a peeved elephant might do, and he'll get shot.
