Final answer:
Evidence that whites cannot be trusted by Indians includes historical accounts of violence and betrayal, such as the murder of George Howe and the aggression between Lane's men and the Secotan tribe, as well as broader policies and attitudes that undermined Native American land rights and sovereignty.
Step-by-step explanation:
The evidence that whites cannot be trusted by Indians is multifold and steeped in a history of broken treaties, deliberate violence, and cultural imposition. For instance, the brutal murder of George Howe by the Secotan tribe was a direct result of the hostility nurtured by Lane's men, who had previously murdered the Secotan chief, Wingina Pemisapan. This illustrates a betrayal of trust and a cycle of violence that would have suggested to the Indians that whites were violent and not to be trusted.
Similarly, Neolin's vision portrayed the British as an obstacle to the Indians' heavenly route, further declaring that the Indians' misfortunes were a result of adopting white ways and thus advocating for the removal of British influence. Additionally, the paradox of black Americans' distrust in the white race reflects the broader sentiment of oppression and betrayal felt by non-white races in the context of historical prejudices perpetuated by white superiority. The U.S. Native American policy under President Washington and the consistent expansion of white settlers into indigenous lands, often ignoring treaties, further underscores the unreliability of white promises.
