"and whenever these great objects are not obtained, the people have a right to alter the government, and to take measures necessary for their safety, prosperity and happiness."
This is an acknowledgement of a right that people as a whole have.
Individuals do not have this right, neither do small groups of people supporting a common cause.
And the moment a group of people begins to infringe upon someone else's rights, by causing harm to
other people's safety, prosperity, or happiness, in a violent manner, their
group changes from being a "protest" into an "illegal assembly", And every person participating in that
illegal assembly is essentially aiding and abetting the terrorist acts against the public and the business owners.
