Yeah, Santa Ana and Garden Grove have high Hispanic population, and Asian immigrants.
It is my observation that most criminals tend to prey on their own kind and in their own neighborhoods. But this is just anecdotal I have little data to support that notion.
By that I mean, poor prey on the poor, the rich prey on the rich, white suburban kids break into homes of white suburban kids, Blacks against Blacks, Hispanics against Hispanics, murderers murder loved ones, etc.
Of course, armed robbery of convenience/liquor stores might defy this theory - robbers go where the money is.
garden grove westminster is full ope vietnamese-amnericans. i doubt many of them are immigrants they have been in the areas since boat people but that was three generations a go.
