A bogger has been keeping track of all the political/social opportunists and their crazy "theories" about why the Virginia Tech shooting happened.

(Hat tip to Denialism.)

[update:  A commenter at the site puts up this excellent link to an old story that illustrates how very not new this phenomenon is.  A public school is dynomited in the late 1920's by a crazed man angry about taxes used to build the school. There are also links to news stories about the event from the time.]

I leave you with a quote from "I've Got a Theory" from the musical episode of "Buffy the Vampire Slayer"

"I've got a thoery.  It could be bunnies...Bunnies aren't just cute like everybody supposes.  They got them hoppy legs and twitchy little noses, and what's with all the carrots? What do they need such good eyesight for anyways?  Bunnies!  Bunnies! It must be Bunnies!"
