cha vang murder: no hate crime charge?

I just received this press release from the Asian American Justice Center... the AAJC, Hmong National Development, Inc. (HND) and the Southeast Asia Resource Action Center (SEARAC) are disappointed that law enforcement authorities did not charge James Nichols with a hate crime for the murder of Cha Vang in his preliminary hearing in Marinette County, Wisconsin last week: National Asian American Organizations Concerned With Omission of Hate Crimes Charge in the Murder of Cha Vang. Nichols has already been charged with first-degree intentional homicide, being a felon in possession of a firearm and concealing a corpse, and he will be formally arraigned on March 19. But with no hate crime charge?
