The WTO riot in Seattle was organized at Prag Tri farm, one of the properties held by the Evergreen land trust association.
They are still using these properties to organize riots. ANTIFA and BLM organize at these properties and they are part of a network of land trust associations across the country used to organize subversive activities.
Why a land trust? Because the properties cannot be confiscated because of illegal activities. The land trust shields them from asset forfeiture.
