The text seems to be a play on the word 'Indian', potentially referring to both Native Americans and people from India, with a possible underlying commentary on historical trust issues involving government treaties with Native American tribes. However, without further context, it's not clear if it's exploiting different meanings of the word 'Indian' or if it's simply a statement with a sarcastic tone. Therefore, it's ambiguous whether this is a pun or not.
You CAN trust the government . . . ask any Indian .
