Your cynicism is understandable but we can just as easily ask “why did he wait so long to cash in on his experiences?” if we are assuming that he’s just trying to make a quick buck.
Landis is 88 years old now. He could’ve wrote a book decades ago and had more time to enjoy his earnings if he didn’t wait 60 years.
So I’m more inclined to believe he’s coming clean because he’s near the end of his life. Which isn’t unusual for people who keep secrets after experiencing a traumatic event. When he says he experienced PTSD after the Kennedy assassination, I believe him. Can’t imagine how I’d feel after seeing someone’s brains blown out in front of me…
No. You'd don't handle a situation like that. He was a government official. Any official would have seen the bullet, picked it up, and reported it immediately to a superior or colleague. You DON'T pick it up, lay it on a towel, and walk away from it and THEN decide to write a book about it 60 years later. It sounds like pure bullspombleprofglidnoctobuns.
And if the quotes and disclaimers I pulled from the VM article mean nothing to you, then it sounds like you're one of the many others who fall for stuff like this.
