The comparisons are somewhat eerie in that there was initial confusion of how many gunmen there were, the shots were fired from above, and just blocks away from Dealey Plaza. The injured were taken to Parkland Hospital. Also, one officer was killed after JFK was assassinated.
At the end of the day, the story comparisons end there.
The bravery of the Dallas police is what is evident today.
But Dallas is indeed a city that seems to be in the target of bad luck. True, it means nothing, but many who are over the age of 50, and have lived through it, are sensitive to the history. That is the only point here.
The similarities are true, but likely just coincidence.
