It cost b/w $25,000 and $80,000 per year to house an inmate, depending on the state. You could have a Mentally Ill person live beside you or near you without treatment break in your house hurt you or kill you maybe & they suffer natural consequences and go to jail because YOU said it was a made up illness and they are just weak. Now, you are wounded or dead and you still have to cough up major dollars to pay for his incarceration. You WILL pay one way or the other, so treat them, it is usually cheaper by far. Or you could move to an island and start a new country yourself genius, unless you are so naive you believe you can change everything in this country. Grow up!
