What proof do you have that we're in the "End of Days" time of history? There has been no event that matches any of the biblical claims of calactysm or suffering worldwide. None of the plagues or marks have appeared. Various Christians have been saying it's "the end of days" for thousands of years. We're still here.

It's terrible that these people (I'm unable to label them guerrila fighters, insurgents, freedom fighters, or rebels) are resorting to tactics like this. This is the true meaning of "terrorism," because they're making people fear being the next person grabbed and murdered.
This is still a frickin' war. The hostilities did not end when President Bush said they did, that was just a way to boost his ratings at home. A war is still going on and the American enemy is still kicking.
Note I did not state that muslims, middle easterns, or other labels to the perpetrators. These guys are simply murderers.
