You really should talk to a therapist about your Boomer KGB paranoia. 
I forgot his name so I looked it up.
"Sam Kinney" is the name of the deceased SS agent who had a similar story about bringing a bullet to Parkland hospital:
I don't believe CE399 ended up at Parkland by chance. I believe someone placed it on a stretcher. Whether it was Landis or Kinney, I don't know.
Between these SS stories and the glaring Chain of custody problems, we can reasonably doubt that CE399 is the bullet that struck both Kennedy and Connolly (if they were struck by the same bullet). It may not even be the bullet that was found on a stretcher at Parkland.
"Sam Kinney" is the name of the deceased SS agent who had a similar story about bringing a bullet to Parkland hospital:
Even you must admit that story is absolutely bonkers, without a thorough investigation of the crime scene, and knowing the full extent of the injury to Kennedy and the injury to Connally, there is NO way to know what type of bullet to bring because of so many random variable factors.
What if an extra bullet turned up?
How at that stage could any one possibly know the true extent of the injuries?
How could they know to flatten CE399 on only one side?
How could they know only a small amount of lead was left in Connally?
How could they know to remove a small amount of lead from CE399 to equal the small amount of lead in Connally?
Here are some random bullets, which one to choose? Hmmm?
The one with one side flattened?
The one with missing lead?
The one with not so much missing lead?
The one with the deformed nose?
