Maybe we will learn more about the 11/2/63 planned attempt on JFK in Chicago, and the 11/18/63 attempt in Tampa. Both were discovered and broken up. Dallas on 11/22/63 was attempt number 3 that month.
The Chicago hit was foiled when a CIA informant named “Oswald” contacted the only black secret service agent, Abraham Bolden, and provided him a heads up with specific details to get the agency to take action.
