Adversities such as being homeless and going to prison has made many people stronger.
I was in prison, and you came unto me. Verily I say unto you, inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.
~(Jesus Christ) Matthew 25:36, 40
Governments have tried to stop crime through punishment throughout the ages, but crime continued in the past punishment remains. Crime can only be stopped through a preventive approach in the schools. You teach the students Transcendental Meditation, and right away they’ll begin using their full brain physiology sensible and they will not get sidetracked into wrong things.
The object of punishment is prevention from evil; it never can be made impulsive to good.
The thoughts of a prisoner - they're not free either. They keep returning to the same things.
