Is Sedition a crime in the US?
Sedition is a serious felony punishable by fines and up to 20 years in prison and it refers to the act of inciting revolt or violence against a lawful authority with the goal of destroying or overthrowing it.
BLM and Antifa groups are committing acts of sedition, therefore they should be charged with this serious felony. Also, the President could also call for the Insurrection Act.
Sec. 334. Proclamation to disperse
Whenever the President considers it necessary to use the militia or the armed forces under
this chapter, he shall, by proclamation, immediately order the insurgents or those
obstructing the enforcement of the laws to disperse and retire peaceably to their abodes
within a limited time.
