But there is a more compelling reason to arrest him. The devil is in the details. Read, for instance, page 20 of the indictment, where prosecutors note that Stone emailed one witness and called him a “rat” and a “stoolie” and threatened to take that witness’s dog away from him. In another email that same day to that same witness, according to the indictment, Stone wrote “I am so ready. Let’s get it on. Prepare to die [expletive].”

Law enforcement simply does not hand a summons to someone who threatens to kill a witness and trust that person to act responsibly with it. No conscientious prosecutor would think a summons appropriate there, or think that a threat to kill a witness is simply what targets of grand jury investigations routinely do.

The witness tampering alleged here is more than just someone asking another, “pretty please,” to lie. Rather, it includes a death threat against a witness: “Prepare to die [expletive].”
