Just Wondering

Last night I watched part of the American Experience program entitled “Oswald’s Ghost” which aired on PBS. The program was about President Kennedy’s assassination. It also talked about the assassinations of Robert Kennedy and Martin Luther King. Ahh, the 60’s, what a time to grow up in America. One day you're happily playing baseball, the next you're in a jungle killing people.

Watching the program I started wondering about the statistical probability of four (if you include Malcom X) prominent political figures of similar political leaning all being assassinated. All within the span of five years. All were for civil rights. What are the odds of this happening?
