Quote #4
With a lawyer present, the likelihood that the police will practice coercion is reduced, and, if coercion is nevertheless exercised, the lawyer can testify to it in court. (Opinion.III.7)
Having your attorney with you gives you a little more power, because the police are less likely to do something that violates your rights when your lawyer's watching. The Miranda rule balances the scales a little bit.
Quote #5
The rule announced today will measurably weaken the ability of the criminal law to perform these tasks. (WhiteDissent.IV.7)
Justice White thinks the balance of power is tipped a little too far by the new ruling. It handcuffs law enforcement instead of the criminals. Warren's Opinion focused on the loss of power a suspect feels while in custody, while the Dissents were more concerned with the police's power.
