Okay so it was not likley due to schizophrenia psychosis as per my initial assessment. Also multiple sources now coming out saying he was on meth. He was a monster, triggered by drug use. In other words, if he was not on drugs he may have lacked the courage to carry out the attacks. Drugs are the problem here, do not wash this barbaric act of violence out through 'mental illness'.
Also this is not about my personal experiences. We listen to woke psychiatrists who have no idea and nod our heads in agreement.
This was a sick man, who chose meth and other recreational drugs over his prescribed meds and all the help the system offered him. He chose meth because it made him feel good. Plain and simple.
