wayback when the "boat people" vietnamese were brought to cali i heard rumors like this but saw my grandpa, dad & uncles tell these same to quit hunting everything that moved on our land with no legal right. Happened more than once & were privy with info from local game&fish guys. 

 not judging here! Different cultures & i think they came from living of the land like my fam. They didn't really cause too much of a problem, main concern was wayward bullets. How could i expect them to eat supermarket processed when i won't!
