Bailing someone out of jail who has a history of untrustworthy behavior can create headaches. You're essentially agreeing to put up 10 percent of a bail bond that could be tens of thousands — or even hundreds of thousands — of dollars. If they fail to show, then you went to all that extra trouble for nothing.
No - if you signed the bond it doesn't matter whether you have a job or not - or whether the bondsman asked you if you did. You are liable as surety on the bond - having a job or not has nothing to do with your liability. Sorry.
No Bond Hold This could happen if the defendant is considered a flight risk, poses a danger to others, or if there are reasons to believe they may tamper with evidence or intimidate witnesses. In such cases, the judge may issue a “no bond hold,” which means the person will remain in custody until their trial.
If he's still incarcerated and bail is $0 than he can't be bailed out. If there are no charges pending but he is still incarcerated then he likely took a plea and is serving a sentence.
