ok then develop a new class of social worker and train them to handle psychotic episodes with calm and gentle manners, using force only if matters get out of hand
Ya stop using the term 'social worker' That is a specific professional designation that describes a person who has a specific degree from a University. Their training, generally speaking, is focused on helping individuals access social programs.
You would need at least a Psychiatric Nurse or a MA/PhD level Psychology student with training working with patients suffering from disorders that can include psychosis.
Even then, without the ability to administer a drug to combat the psychotic episode, which of course could take hours to days, there is no guarantee that 'talking calmly' will work. People having hallucinatory events will not necessarily be able to comprehend language or interpret intent. Moreover accompanied by delusions it can be damn near impossible to reason with them.
Instead of using live ammo and tasers they need to use elephant tranquilizer. If they can get a clean shot or maybe gas. And then have the time for it to take effect.
