Was Stanton a murder target?

[Gene C]

There was a lot of paranoia going on at that time, with conspiracy rumors (some true) all over the place.

I agree with SSlater, so I'll pick up where he left off.
6. Thomas Jones isn't the model of honesty that many seem to make of him. He had a biased sense of virtue and values. He also wanted to sell his book.
Stanton may have been on the "hit list", but he wasn't high enough on the list.
7. The letter you mentioned is hearsay. I am a bit surprised you even offer that as an arguable point.
8. There were suspicious people everywhere in Washington in 1865.
9. What does killing Grant accomplish?

I can agree that Stanton should have been a target, but in my opinion he wasn't. At that point in time, now that the war was over, a severe shortage of dedicated confederate martyrs and assassins to go around.
