IIRC Dorothy was investigating the mob hit angle. She was about to go to New Orleans and interview some mob associates about it when she “tragically overdosed”. (I’ve read the details of her death and they stink to high heaven).
For anyone not in the know of THIS story, it goes something like this: Joe Kennedy makes a deal with the mob that if they help get Jack elected, then JFK will leave them alone while he’s in office. The mob pulls some dem worthy shenanigans in a few states, and gets him elected. He then appoints RFK as AG who promptly announces that he’s going to bust up the mob. The mob feels betrayed by this and orders a hit on JFK and later RFK as well for retribution.
You know why Dutch Shultz was taken out by the mob? Because he wanted to kill a local DA. The mob had rules and one of them was don’t kill cops, judges, or law enforcement of any kind. They knew it would cause them more trouble than it was worth. Now, you say that exact same mob wants to kill the president!
I don’t think so.
