Why did the protestors who participated in The Boston Tea Party dress as Native Americans?

None of the choices are really satisfactory. Indian disguises for the Boston Tea Party as well as other protests and demonstrations in the colonies were a common practice. Some were as crude as smearing red coloring on the face and wearing a bandana. Some theorize that those disguises that took on Mohawk characteristics were related to a Masonic use of the Mohawks as a symbol of liberty. In the tightly controlled near island of Boston of 1773 it is doubtful that anyone would believe that actual Indians would have snuck in for the purpose of destroying a shipment of tea.
