Final answer:
The Fifth Amendment guarantees the right to be indicted by a grand jury for capital crimes, but this requirement only applies to federal crimes and not to the states.
Step-by-step explanation:
The Fifth Amendment guarantees the right to be indicted by a grand jury for capital crimes. However, this requirement only applies to federal crimes and does not extend to the states. Instead, many states have their processes for determining whether there is enough evidence to hold a trial, such as a preliminary hearing before a judge. Therefore, not all states guarantee grand jury indictments. This divergence reflects the autonomy of states in shaping legal proceedings, showcasing how state systems differ in assessing trial eligibility compared to the federal requirement of a grand jury indictment for certain serious offenses.
