Officials in Dallas, Texas, where former President John F. Kennedy was assassinated, want to honor the 50th anniversary of his death with a celebration of his life in 2013.

But conspiracy theorists who believe government officials played a role in his demise on Nov. 22, 1963, refuse to be sidelined, reported the Wall Street Journal.

Those theorists have staged an event at Dealey Plaza, where Kennedy was shot, every year since 1964. But they were not granted a permit for the event next year, and Dallas officials plan to use the plaza for readings of Kennedy's speeches. The planned ceremony also includes military jets flying overhead.

"Our First Amendment rights are being violated," said director of the Coalition on Political Assassinations, John Judge.

Dallas Mayor Mike Rawlings told the WSJ that he would meet with the coalition but emphasized that the ceremony would focus on Kennedy's life, "not the moment 50 years ago."

One individual interested in alternate theories of Kennedy's death, Pete Johnson, started -- a reference to one theory involving a second shooter -- in an attempt to encourage people to go to the plaza next year during the ceremony.
