In Introduction to Criminal Justice, criminal justice is seen as following stages: prearrest investigation, arrest, post-arrest investigation, preparation for trial or entry of plea, conviction, disposition. These stages led Herbert Packer, justice expert, to think the criminal justice as an assembly line conveyer belt. During the criminal justice process, the offenders and the crime are being treated as cases. And the system would determine the type of case, then use necessary execution and move on to the next case. While this operation system solves cases faster and easier, it could also result in negative effect. The operating system is made by us the human, so it will sometimes have some problems. The biggest problem with the assembly line is overlooked of unique cases. During the assembly line process, one of the agencies might overlook or ignore some of the unique cases that occur. And as the assembly line goes on, the unique case becomes a problem. At that point, no one would ever look back at the case, and apparently, convict the crime. The offender could be treated unfairly, or the victims couldn’t get the justice they deserved. For instance, on the HuffPost, it stated how “researchers found that 149 people were cleared in 2015 for crimes they didn’t commit”, and “139 people were exonerated in 2014′. This clearly shows that amount of wrong crime has been increasing. Another example is the wrongful conviction in Montana. A person names Jim Bromgard was arrested due to an attack from a young girl. Mr. Bromgard spends his time in prison for fourteen years. It isn’t until he did a DNA testing to prove his innocence. That goes to show that the criminal justice system has some flaws since some cases are being treated unfairly.In conclusion, the criminal justice procedure is efficient but can sometimes bring negative outcome to our society. Surely ever procedures are not perfect, but until people find a solution, there will always have flaws in the criminal justice system.
