Not that that is the reason.
What difference does the race of these creeps make. From the description "white...long hair" my bet would be on enviro-terrorists. Ted Kaczinski wannabes. Long past time to take those creeps (and their World Wildlife Fund, Sierra Club fellow travellers) down. Even if this fire wasn't their doing (and it's got their M.O.: burn the urban development that threatens the environment; "we must burn the forest in order to save it").
