That schizophrenic meth addict deserves help as much as anyone else does. Drug addicts don't become drug addicts just because we can: and mental health disorders are pretty much always comorbid with addiction.
What's relevant is the proposed tech empowers the average person the street to quickly access and synthesize already public information. It's essentially no different than a real-time background check.
And I would almost certainly think that you'd agree that in a situation where your personal safety is potentially at risk, that you'd prefer to have this information available to you. If you were hiring a baby-sitter for your kid, would you not conduct a background check. If the background check revealed that said babysitter was a schizophrenic meth addict, would you still hire that person?
Of course not. That person needs help, but you as a private individual going about your life is not the entity capable of providing it.

Does that not imply op suggested otherwise?
Besides, the school system needs more than just money, just like the "homeless problem". I don't feel comfortable passing judgement on one class of people vs another solely because of the circumstances they were born into.
The part 'vs another solely because of the circumstances they were born into' from the parent post does not reflect what the GP post actually says. The GP was solely arguing on the practicality and the costs and benefits of doing it; solutions to problems have trade-offs, it is no good wishing them away.
That said, how the homeless are treated in a lot of rich nations today are a complete disgrace. Increasing a well off persons well being is worth far less than increasing a not so well off persons well being IMO.
