Pass all the laws you want. Unless you have the psych beds and providers willing to do the exams they will continue to languish in jail.
Minnesota is an example of good intentions not being fullfilled.

QCP - it is a scandal present in most states. I toured our local ER 3 years ago. They have a wing with 10 psych beds where people wait, (locked room, under observation and no windows) for weeks waiting for a bed. The state institutions were mostly closed in the 70's and 80's cutting beds. People in jail seem to be on the lowest part of the totem pole for care.
