The role of science in criminal investigation has increased tremendously since the landmark decision in Miranda v. Arizona (1966), which limited the power of the police to interrogate suspects without a warning of the right against self-incrimination and the warning that any confession could be used against the suspect. Miranda so limited the ability of the police to solve cases by confession that new methods of providing the circumstantial link between the suspect and the victim or crime scene were needed. Certainly, science had been employed in crime solving for decades or even centuries, but only after Miranda was the true power of science to solve crimes recognized.
