“Sedition is a term of law which refers to covert conduct, such as speech and organization, that is deemed by the legal authority as tending toward insurrection against the established order. Sedition often includes subversion of a constitution and incitement of discontent (or resistance) to lawful authority. Sedition may include any commotion, though not aimed at direct and open violence against the laws. Seditious words in writing are seditious libel.”
It happened before and it darn well could happen again.
Sedition is should not be a crime unless it presents a clear and present danger to the civic peace.
