What happens after an arrest for knife laws in California?
How release before trial works in California: Each county superior court adopts a bail schedule under Penal Code § 1269b; it fixes the amount on which a person arrested without a warrant may be released before appearing in court. After the first court appearance, the amount of bail is within the judge's discretion and may be higher or lower than the schedule, subject to Penal Code § 1275 and controlling case law, including In re Humphrey (2021) 11 Cal.5th 135. Persons not entitled to bail are those charged with capital crimes when the facts are evident or the presumption great; felonies involving acts of violence when the facts are evident or the presumption great and the court finds by clear and convincing evidence a substantial likelihood that release would result in great bodily harm to others; and felonies when the facts are evident or the presumption great and the court finds by clear and convincing evidence that the person threatened another with great bodily harm and would likely carry out the threat. For serious and violent felonies and certain domestic-violence and stalking offenses, release on bail in an amount other than the schedule requires a hearing in open court. At arraignment the judge may release a defendant on his or her own recognizance, release under supervision, set bail, or not set bail; typically, someone charged only with misdemeanors will be released on their own recognizance.
