Why is mini Miranda used in certain states only?

The "mini Miranda" warning is used in some states to inform individuals of their rights during custodial interrogations, particularly when the full Miranda warnings are not required. States that implement mini Miranda typically have their own legal standards that dictate when these rights must be communicated. The use of mini Miranda allows law enforcement to balance the need for effective interrogation with the protection of individual rights, often in situations where the full Miranda warning may not be legally mandated. This approach can vary by jurisdiction due to differing interpretations of constitutional protections.
