I kinda agree with Bill.
Just kill Lee Harvey Oswald and be done with it. But then it would probably be only two episodes long.
shareThat only works if Oswald is the lone Gunman acting on his own. Jake still couldn’t be sure of this at time. If Oswald had a partner, or if he was simply hired, killing him would prevent nothing.
Keep in mind, Jake had to invest years in to this mission. If he was wrong, it would take a few years to get back to that point. It’s just not worth the gamble.
