The Hidden Racism of the US Navy

Two US Navy sailors were accused and arrested, I think, of passing secrets to China. One was a machinist mate named Jin Chao Wei, also known as Patrick Wei. The other was a petty officer named Wen Heng Chao,. And when I read also known as Thomas Chao or Zhao, I think I've got us the ZH Zhao. Rob wondered if born Americans who happen to have a particular ethnic heritage do not seem to be automatically suspect unless you got something that tells you keep an eye on that guy?
