is force a necessary element of seditious conspiracy? I believe it is but I am not an attorney.
18 U.S. Code § 2384 - Seditious conspiracy
If two or more persons in any State or Territory, or in any place subject to the jurisdiction of the United States, conspire to overthrow, put down, or to destroy by force the Government of the United States, or to levy war against them, or to oppose by force the authority thereof, or by force to prevent, hinder, or delay the execution of any law of the United States, or by force to seize, take, or possess any property of the United States contrary to the authority thereof, they shall each be fined under this title or imprisoned not more than twenty years, or both.
Breaking it down:
1. conspire to overthrow
2. put down
3. destroy by force
4. levy war
5. oppose by force
6. by force prevent, hinder, delay execution of law
7. by force seize, take, possess any property
Number 2 above, the meaning of “put down” is to stop.
The element that best applies to the conspirators against the Trump Administration is number 1, followed by number 2. The characterization that describes the sedition is “soft coup”.
