I personally believe the miranda warning is extravagantly important to the criminal justice system of the United States because when being out into police custody you should at least be read your rights which is technically what the miranda warning is. It's given by police to the suspect that they are obtaining into their custody to question that you don't have to speak especially if you're lawyer is not there and if you can't afford a lawyer you will be provided a public defender which is a given right of every American. I believe this law is out in place to keep people safe because people don't always know what to say when nervous, and it goes to say that words can always be twisted and used against you in the court of law.
