South Boston woman charged with that attack on a disabled person at Harvard Square T stop

Just another example of someone who for their own good and society in general needs a session of long-term care

Back more than 50 years ago the medical / psychiatric profession thought that the new Era of Antibiotics and Vaccines enabling infections to be cured and viral scourges to be prevented -- implied a corresponding new Era of Anti-psychotics curing mental illnesses with chemicals

Well it didn't .. .the jury is now in .... Case closed!

A bit later [late 60's] we had the exposure of some serious excesses in Mental Health facilities operated by the states [e.g. Titicut Follies about Bridgewater]
from the wiki:

Titicut Follies --- a 1967 American Direct Cinema documentary film directed by Frederick Wiseman and filmed by John Marshall, about the patient-inmates of Bridgewater State Hospital for the criminally insane

Add them together and M. Stanley and company followed through in the 60's and 70's and dismantled the Commonwealth's network of mental health facilities and dumped their contents onto the street

As a result --- We've been "benefiting" from people who are not able to control their actions in public or private for decades. Most of the time its just an annoying outburst, or someone talking without a cell phone [e.g. on the Common or the T] or some mild vandalism.

Occasionally, the individual is "triggered" by something most often innocuous or perhaps voices in their self dialogue to act violently [e.g. this event on the T, or the recent recidivism by a convicted child rapist who was declared sane by the Mass State Supreme Court and ordered to be released]. Unfortunately, rarely their freedom results in catastrophic violence [such as the case for many of the mass shootings].

Its time to roll back things and admit our hubris -- We don't have the tools to enable these people to live in public -- unfortunately, there is no GPS bracelet for someone whose wiring is fundamentally flawed.

Don you live in a cave?. South Boston has a large minority population for the last 15 years. Get out once in a while.
