Best advice I would think would be to keep your own house in order. No drugs, no drinking, no knock-down domestics, no problems with kids acting out, etc. Don't put yourself in a situation where you would need to call the police for help. Talk out your marital problems or separate yourselves for the night. Know what your kids are doing, where and with whom. Know the traffic laws in your area and keep to them. Pay your bills, don't steal and don't give anyone else a reason to call the police on you. Be civil and respectful to everyone you meet and sever ties with anyone who can't treat you the same way.
