Bulldozer attack driver shot dead in Jerusalem writes Reuters:

A bulldozer driver went on a rampage in Jerusalem on Tuesday, hitting vehicles near a hotel where U.S. Democratic presidential candidate Barack Obama was due to stay later in the day, before he was shot dead.

Bulldozer? The pictures from Jerusalem show a small front-end loader or backhoe which may weigh some 2-3 tons.

A bulldozer is something like this.

It weighs about 50+ tons. The Israeli army has several of these up-armored Caterpillar D-9s. It uses them to flatten Palestinian homes in the illegally occupied territories and to kill people like Rachel Corrie.

The Israelis indeed bulldoze in the original meaning:

bulldose "a severe beating or lashing," lit. "a dose fit for a bull," a slang word referring to the beating of black voters (by either blacks or whites) in the 1876 U.S. presidential election. A bulldozer was a person who intimidates by violence until the meaning was extended to ground-clearing caterpillar tractor in 1930.

That is, when they do not shoot non-violent and bound Palestinians.
