The answer is in Schall v. Martin

Explanation:

In Schall v. Martin, the Supreme court supported a New York statute in which it was allowed the preventive detention of juveniles that were accused of a crime, and at the same time, these juveniles were considered a "serious risk" because they could commit other crimes before trial.

Schall v. Martin is considered the first time in which the Court sanctioned person's detention before establishing a person's guilt. This was made to ensure that the person would be at trial.
