Peaceful assembly to express opposition to an injustice is a protest.

Peaceful and public violation of an unjust law is civil disobedience.

Mass violation of just laws protecting persons, private property, and public property is a riot.

It is a disservice to the language to call a riot a protest.

It is a disgrace to the cause of honesty to call a disturbance “mostly peaceful” just because fewer than half of those involved are throwing bricks, stopping traffic, burning stores, brandishing assault weapons, or assaulting passersby.
