There are plenty of Asians up north. Any nationality can have a criminal element. We are talking about homeless people. In most cities they are white and some black. The majority of them. You can have hispanic or Asian homeless, but it's going to be a much smaller number in ratio. I don't think I have ever seen an East Indian homeless person.
By the way, white people are more offended by the term Oriental than Asian people. Political correctness can cause people to put on a facade of deep concern. If you look at many of the Native American tribe websites, they do not call themselve native americans. They call themselves Indians.
