We don't know for sure if the murderer is a Vietnamese. Even if the killer were in fact a person of the Vietnamese origin, it's not sensible to label the whole Vietnamese race as criminals. Where are your senses, people?
We are all angry at this senseless criminal act and we are all feeling sad for the lost of two young lives. We hope and we urge the police to catch and convict this murderous individual, may he be Vietnamese or Chinese or anybody of any origins, but let's not blame the whole Vietnamese community, and let's not blame the ordinary Vietnamese shop and restaurant owners.
