what amendment you can bail
The Eighth Amendment (Amendment VIII) to the United States Constitution is the part of the United States Bill of Rights (ratified December 15, 1791) prohibiting the federal government from imposing excessive bail, excessive fines, or cruel and unusual punishments, including torture.
In Stack v. Boyle, 342 U.S. 1 (1951), the Supreme Court declared that a bail amount is excessive under the Eighth Amendment if it were a figure higher than is reasonably calculated to ensure the defendant's appearance at trial.
