Seems like maybe it's time for a new hostage strategy:
Kill a hostage, get a new parking lot in the known or suspected vicinity of the act or the perpetrating sponsor.
Take a hostage, fail to release the hostage when asked, get a new parking lot, even if the hostage has to die in the process.
If people know they might die suddenly and almost capriciously if they allow hostage-taking terrorist scum to fester or even merely maneuver in their midst, they might start taking their responsibility to join civilization seriously.
Perhaps when Kerry is elected to replace the wimpy Bush administration, he'll give us some big national gonads enough to scare the bastards into becoming human.
