This weekend, the FBI busted a Los Angeles man named Chad Conrad Castagna for sending threatening letters filled with non-poisonous white powder to House Speaker-elect Nancy Pelosi as well as New York Senator Chuck Schumer and several media and entertainment figures like David Letterman, Keith Olbermann, and Jon Stewart. According to the Associated Press, some of the letters included the phrase "Death to Demagogues."

The choice of targets seems to suggest a thing or two about Castagana's politics—all of the recipients are highly influential liberals who came to the fore this election season, particularly Olbermann who spoke about the New York Post's poo-pooing of his possible 'thrax attack earlier this year despite their own brush with the white stuff. AP lists Castagana's job as "unemployed," but not much more is known about him. And that's where the Web comes in.

Castagna, 39, has some curious netroots, and not in politics. Here's a letter he wrote to B-movie historian Joe Bob Briggs:

Whatever happened to that magnificently voluptous actress , Charlie Spradling ? She starred in some movies in the early 90's (MERIDIEN, PUPPETMASTER 3 , MIRROR MIRROR , SLEEP WITH A VAMPIRE) then she quickly faded from view . The last I saw of her was in this sleazy movie CONVICT 972—apparently she has stopped doing topless roles after the early 90's . Is she still making movies ? Is she married ? Or is she dead ?

Those 'perfect' breasts of her's can't be real . . .

Turns out, she worked as a stripper and married the guitarist from Pretty Boy Floyd. No word on whether her breasts are real or not.

Then there's this comment he posted on the blog Hott for Teacher about the arrest of student-seducing teacher Pamela Rogers that displays both his tendency to add a space before punctuation marks and his opinions of the criminal justice system:

Pamela Rogers shoild [sic] get some prison time (she is in jail now) for violating her parole .

The issue here is trust, she cannot be trusted to keep away from this teenage boy .

Beyond that, she is a nitwit !

She displays an almost juvenile mentality when getting caught; first smugness, then when she realizes she is going to due [sic] some hard time, she cries like a little kid that's about to get spanked !

She can get, and should receive psychiatric treatment in prison . . .

Sounds like Castagana might pioneer the use of blogs as an insanity defense. He's probably wrapping up a post and copping a plea right about now.

UPDATE: This post has been updated with the correct spelling of Chad Conrad Castagana's name.
