My first and final answer to this question has to be "NO", but Truther.org disagrees with me.
The website pulls out all the crazy in arguing this ridiculous and tasteless conspiracy. They reference SKYNET killer drones operating in the United States and blame the West, TX fertilizer plant explosion and the death of 19 firefighters during an Arizona wildfire this summer on government drone strikes.
But why would the American government want to assassinate Paul Walker? That's simple. It is a ploy by the Obama administration to get the phrase "Fast and Furious" out into the media, thus desensitizing Americans to hearing it. Then the government will sponsor a terror attack related to Operation Fast and Furious, and use it as an excuse to take everyone's guns. Genius.
I love a good conspiracy theory as much as the next guy, but these folks over at Truther.org should be using their talents to write fiction. They are coming up with Orson Scott Card levels of crazy shit over there.
Edit: Some have been questioning whether Truther.org is a parody website. Here is what the About Truther.org section has to say:
Truther.org is a false-flag/state-sponsored terror whistleblower website which serves as a conduit for worldwide peace related news and information. Truther's motto is "Peace by Revelation", with the stated purpose of obtaining world peace though non-violent pro-active peace action.
Blessed are the Peacemakers.
And who is the author of this website?
David Chase Taylor is an American journalist and the editor-in-chief of Truther.org. Taylor currently lives in Zürich, Switzerland where he has applied for political asylum after the release of The Nuclear Bible, a book credited with foiling a state-sponsored nuclear terror attack upon Super Bowl XLV in Dallas, Texas on February 6, 2011. Taylor has also authored The Bio-Terror Bible, a book and website exposing the 2013 global bio-terror pandemic. To date, Truther.org has identified and exposed over 50 Obama sanctioned terror plots, as well as the Alex Jones' links to STRATFOR.
