A more thorough explanation:

Definition: A bailer is someone who provides bail for a criminal defendant's release. They act as a surety, meaning they promise to pay a certain amount of money if the defendant fails to appear in court.

Examples:

• John's friend acted as a bailer and paid $10,000 to get him out of jail.
• The bailer was responsible for ensuring that the defendant showed up to all court appearances.

These examples illustrate how a bailer is someone who helps a defendant get out of jail by providing money for bail. The bailer takes on the responsibility of ensuring that the defendant appears in court, or else they will have to pay the full amount of the bail. This is an important role in the criminal justice system, as it allows defendants to be released from jail while they await trial.
