Please remember the APA voted to torture and destroy the minds of people who wore Casio watches, and assisted in that torture program. (All anyone needed to be arrested under the bounty program was to be in a suspicious area or to have a highly accurate clock or watch. No actual evidence of wrongdoing was required.)
Many practitioners had absolutely no problems with abusing their knowledge and ability, not against actual terrorists or even people from the same nation as the terrorists, but against easy targets. The banality of evil, demonstrated to a high degree.
If an organisation can commit acts of utter depravity and evil on whim, then a whim is all that is needed.
This doesn't mean it will happen, but the APA has shown no obvious signs of maturity or rationality, only excuses. And that's not a good position to be in, when the head of state has licensed ICE to gun down people without cause and has promoted the wellbeing of diseases like measles over that of the citizens.
I don't believe forcible injections are likely, but I'm also not going to say that psychiatrists have been earning trust these past 26 years. Personally, I think forcible injections won't happen, but not because psychiatrists have discovered ethics. Rather, because it just isn't practical.
