This week, a new movie is being released that tells the story of controversial experiment done more than 40 years ago.

In August 1971, 24 men in California were chosen to participate in a psychological study administered by Stanford University, "The Stanford Prison Experiment." The main focus of the study was to show the type of behavior one develops while imprisoned and the type of behavior one develops when they are the prisoner.

With 12 men posing as guards and 12 as prisoners the experiment lasted only six days, after violence became the norm and several volunteers dropped due to mental stress.

It begs the question, does the prison dynamic change not only affect the incarcerated but the people who guard them? Psychologist Dr. Jeff Gardere and Gary Heyward, author of the book "Corruption Officer," discusses about the effects of prison life.
