Actually, the theory that JFK was murdered for EO 11110 has been debunked, all it did was delegate the power to issue silver certificates to the treasury should the need arise:

Also, the EO stayed in effect until 1987.
I am not trying to be contentious just want to clear up this myth. I despise the Federal Reserve but this claim is a distraction from some of the real reasons that Kennedy was publicly executed. I plan on writing about these in the future.
It's not a coincidence that 3 of the presidents that tried to implement a different monetary reform in the U.S. were murdered.
I just posted a post about the FED. If you are looking forward to see my argument.
