 For example, if a person is charged with four crimes, unless the evidence is connectable to each crime, each piece of evidence can be used only in each separate crime and not to link any crime to another.In law, bootstrapping can also refer to an attempt to gain jurisdiction over a non-jurisdictional matter by its circuitous relationship to a jurisdictional matter.In 1987 the Supreme Court determined that the "bootstrapping" rule did not survive the adoption of the Federal Rules of Evidence.
