The guy who stabbed people at 10am in front of the Nordstroms downtown flagship store, took several steps to evade capture, hide weapons, etc. All indications that he knew he was committing a crime when he stabbed his victims.
Then when the jig was up (as police closed in on him) he stripped his clothes off so we get the "naked man" headline.
Why would he strip his clothes off? Sounds like he was taking deliberate steps to increase the likelihood of being found mentally incompetent knowing that local prosecutors tend to dismiss such cases.
Also, Seattle's city prosecutor and head public defender jointly and publicly admonished a judge that refused to release one of these career criminals when requested to by the prosecutor.
Long term? After the deinstitutionalization movement in the US, it's possible to get people forcibly committed for short term evaluations (a 72 hour "Baker Act" evaluation), but long term involuntary commitment is quite rare.
Seems very odd Wilson managed to dodge both mental facilities and prisons.
