That's probably part of the challenge of understanding this bill. It's not clear, because we don't know how this is going to unfold.
Segregation units, if this is where these SIUs are going to be located, are certainly not a therapeutic environment. The interaction would be through food slots. There are no common areas in most segregation areas, so it's not clear how this human contact will take place, because you'll have to actually physically take the inmates outside of those units in order to find appropriate program rooms or interview rooms.
