OK. Now we are getting somewhere.
Follow this story, and compare and contrast what SHOULD happen with what DOES happen.
What SHOULD happen is that this young man should be arrested and immediately admitted involuntarily to a mental hospital (if one exists in his jurisdiction). A police investigation should discern if he tortures animals, has ever hurt anyone, or uses cocaine or methamphetamine.
His involuntary stay should be indefinite from admission, with the only role of a court hearing to determine if the facts as presented are true or not (did he write the words. etc).
If he has a background of animal abuse or has juvenile offenses involving unprovoked injury to others, he should be locked up for the rest of his life. Any “treatment” should serve the purpose of avoiding injury to staff or other involuntary patients.
If anything he has done constitutes a crime, he should be tried in open court and if convicted given a sentence consistent with the crime, but with serving the sentence postponed as long as he is confined in the mental health system.
Those damn crisis intervention officers will not involuntarily take these crazy young men to the psych ward unless they are literally about to shoot
