Answer:
A Confession
Explanation:
In the case of Colorado v. Connelly (1986), Supreme Court Justice Wiliam Brennan considered A CONFESSION to be the strongest piece of evidence in a trial.
This is evident when he wrote in his dissent among other things that "Triers of fact accord confessions such heavyweight in their determination that the introduction of a confession makes the other aspects of a trial in court superfluous and the real trial, for all practical purposes, occurs when the confession is obtained."
