Well, in the first place, they weren't actually crocodiles but alligators. The difference of the two would be that crocodiles are more on the seawater and alligators favor the freshwater. They also have a difference in their head shape where crocodiles are much more like a V-shape rather than the alligators that usually have a U-shape look. Their appearance would also be an indicator since crocodiles are lighter in color where alligators are darker. The US president that kept two alligators as pets would be the 31st president of the United States which is Herbert Clark Hoover.
The federal court system has three main levels: District courts (the trial court), circuit courts (first level of appeal), and the Supreme Court of the United States (final level of appeal)
How has societal viewpoints concerning incarceration and probation influenced human services over the past three centuries?
Answer: I believe that it has changed drastically. The purpose of prisons was to help offenders straighten their lives and reintegrate to society. That is why it was based around three models, Custodial, Rehabilitation, and Reintegration. Probation was a way to help the young offenders by placing them under supervision but it also changed to help rehabilitate regular inmates and reduce crowding in prison.
I hope it helps, Regards.
