The cost of bail can vary widely depending on several factors, including the jurisdiction, the specifics of the case, the severity of the charges, and whether your friend has a prior criminal record.
For charges like assaulting an officer, bail amounts can be significant, often ranging from several thousand dollars to tens of thousands or more. In many cases, bail can be set at an amount that reflects the seriousness of the offense and the perceived flight risk of the defendant.
To get a more accurate estimate, it would be best to check with the local court or law enforcement agency where your friend's case is being handled. They can provide information on the specific charges and the corresponding bail amount. If your friend has a court date, that information could also help clarify the situation.
