Hypothetically, if you were arrested today and needed to tell your closest friends and family what happened, how would you want them to react, as opposed to how you think they will react? You would want them to be concerned, but relieved you are alive and all right. You would want them to support you. You would want them to help you out in any way possible, whether it is bailing you out of jail, picking your kids up from soccer practice, or notifying your employer.
Now think about how you need to react when you learn that a loved one of yours has been arrested. There is no doubt that you will feel angry and disappointed, but remember that they know you are feeling this. What they need from you right now is to know that you will support them and help them in any way you can. They need this reassurance because they are in a very tough spot and they are feeling very vulnerable and helpless. You need to come to their rescue.
Helping them bail out of jail is a very good starting point.
