The horn beeped twice and the second honk was immediately prior to the gunshot by Ruby. The headlights on the station wagon also flashed briefly just at the second honk before the gunshot by Ruby.
Not much evidence of a conspiracy I'll agree, but on the other hand, things were a bit less technologically sophisticated in those days.
The folks who put all of this assassination business together certainly did not anticipate the acoustic evidence, the Zapruder film, and later the Internet, among other things.
I was shown enough compelling information 40 years ago to convince me of the corruption of our system.
Perhaps that is part of the reason that I have since made it my business to know what I am talking about in every case before I express opinions on any matter.
There are guys in Dealy plaza to this day that make it their "business" to sell newpaper flyers at $7.50 thats full of the conspiracy crap. Hate to disappoint, but there was no conspiracy. Most of the theories are woven fantacies to try to make it look like a conspiracy. Take away all the crap of "opinons" and look at it from a forensic standpoint with film and photos and pure logic and the vast majority of the opinions by so called experts can be shreaded to pieces. The only conspiracy of teh JFK assassination is the one that still wants people to believe its a conpiracy.
