Agreed. And the relevant sentences, within the paragraph about CIT:

> CIT officers make up about 15 to 20 percent of patrol officers and receive 40 hours of training that focuses on scenarios derived from actual incidents. Officers receive extensive training in de-escalation techniques.

It's ambiguous whether "officers" in the second sentence refers to all officers or only CIT officers (I read it as the latter). Regardless, according to this analysis only 0.45–3% of all patrol officers receive this training that is specifically with regard to people with mental illness.

Edit in case my math is unclear: according to this research, 3% of all department use CIT or similar. Assuming 100% of officers in those departments receive the training, that works out to 3% of all patrol officers. Assuming only the ~15% of CIT officers receive the training, that works out to 0.45% of all patrol officers.

I didn’t understand why they chose to include that extra information about CIT, but maybe the authors were just being thorough.

I did read it as if it were written: 15-20% of Memphis Police patrol officers are also CIT officers

edit: I’d highlight that the authors did emphasize the intensive nature of de-escalation techniques for CIT training and that perhaps they were singling out Memphis as “state-of-the-art” police policy, at that time, with regard to law enforcement officers being tasked with mental health care.

In reply to your edit, you also need to account for the same training that may or may not be provided in all the other cases. This review article did not highlight any such data, but it likely exists in the research under review or in other available research

Sure — but the point is that given the evidence we’ve discussed so far, there’s no reason to believe de-escalation training is more normative than that disturbing seminar.

There is some suggestion in the presented data that police are asking for normative mental health training.

Can dig into the research to find out if anyone has empirically studied the attitudes of the trainers, themselves.

There is no reason to believe that de-escalation training is less normative than that disturbing seminar, either.
