There's a concept called assertive community treatment teams. Right now there's a police officer that's part of a group of people, including mental health professionals. They'll have a caseload. One team of perhaps 12 professionals will deal with 100 people on their caseloads and actively monitor these individuals to make sure they're functioning, taking their medication, and not developing problems that require them to be taken into care. The concept there, really, is based on the assertive model of community care.
