It's annoying how such racial hate crimes are committed and the felon has zero remorse. Delusional maniacs justifying and 'fighting for peace'. They are heroes in their own minds.
He seems to have zero remorse, as he is having mental issues. He is a known drug user, and was reported to be having mental health problems for a long time. At the time of the shooting, he was high on a drug called Suboxone, which can trigger violent reaction on people who take it. When he comes back to his senses, he will regret for what he did.
It would be a great if you give the link of the news, since the incident has attracted world people and me to know more about it. I still don't get a complete reason why he did that, maybe he is hiding something as the main motive.
