Gretavo Verdadero is owner of the website wtcdemolition.com. The website appears to be one of those fake 911 truth websites intended to paint all 911 truth websites as kooky in the way that sending a smelly unwashed government agent into a crowd of real anarchists gives the impression that anarchists are smelly I've seen posts by this "Gretavo" character on various 911 forums. The main push of his participation seems to be to paint everyone else as a fake 911 truther, which is consistent with the starting assumption of this post.
I began to wonder, just who is this "Gretavo Verdadero"? I found strange videos by Gretavo on Youtube. I found posts by people saying he was smearing them online. Finally, I discovered that "Gretavo Verdadero" has a real name and that name is Gustavo Espada, some person working at Harvard University in IT.
A search on Espada yields an accusation that he is a CIA agent. A little more digging reveals statements he has made online that he grew up on U.S. Embassies in Latin America. Most interesting of all is a statement on his website. If you visit his website, there is a link with the text: "A note to U.S. servicemen and women an other federal agents"
I was kind of curious about why a 911 truther would be posting a note to federal agents, so I checked out that link. It goes to this page: http://wtcdemolition.com/note.htm
On this page, a strange page, is an image that contains text. Now, if you put text in an image, Google won't index it. Near the bottom of the text is the sentence: "The author of this site is an American citizen who has served his country as you now do, and whose sole interest is to preserve our liberty in a time of great danger and deception..."
I don't know about you, but I find this statement very interesting. Specifically this: Espada claims to be someone who has served his county as one of the following, by virtue of the addressees of the link: a U.S. Serviceman or a Federal Agent. Now, I've found no information claiming that he has ever been a U.S. Serviceman, so this leaves "Federal Agent." Interesting?
