Bail bond agents can carry firearms (like regular citizens) and make arrests in California. However, they do not have the same power as police officers to investigate crimes, enforce traffic laws, or cordon off specific areas.
If a defendant cannot afford bail, then at the arraignment or any hearing while still incarcerated the defendant can request a bail reduction or release without bail. That must be supported with evidence that the defendant is unlikely to reoffend or to flee.
Reaching out to a licensed bail bondsman and explaining your situation will ensure that they can handle your case correctly. It's important to explain that you cannot afford the full bail amount and provide extensive details about the charges, bail amount, and any other essential information.
