Not exactly a "top psychiatrist" in my book.
Whatever the Doctor's 'case'; he does not appear to contradict current medical wisdom - albeit; a 'wisdom' ignored. And as bad - or archaic - as ECT appears; it is returning in popularity; inasmuch as ECT does often succeed/out perform; drugs for treatment of deep depression in patients where drugs have not worked or have not been wanted or advised.
Given how often fraud compromises 'scientific inquiry' so as to perp an agenda; we should always maintain a healthy skepticism. The question - the implication of - of 'drug therapies; the 'fact' of drug presence in many of the young 'perps' per murderous campaigns; however; has long been noted. If only to be; dismissed; overlooked; in favor of those MO's which grip; influence and too often; 'drive' popular opinion. This we know; regardless of the public messenger.
We know too; like all 'events' when they burst into our 'reality'; there is more than ONE reason. And politicians with determined agenda's; tend to seize on that; which best serves their MO and goals; while ignoring more the more pertinent; critical and often, simply obvious.
Too many 'crickets chirping'; when it comes to using Alan Lanzas as a 'tool' or excuse for 'left-wing agenda' per diminishing our Constitution; the Rights afforded; contained therein; and punitively targeting law-abiding citizens for exercising their Constitutional Rights. Leftist MO's; designed to disarm and disempower citizens, in the 'face' of Leftist/Marxist/Progressive. . .totalitarian 'will'.
(A negative, ignorant WILL; which of course; by history's own message; is the most uncontrolled; unwarranted; unrelenting and immoral - and addicting - killing power.)
