First, as a family member, you are not allowed to keep quiet if you know that your son or daughter or relative is part of the community. The law forces you to give them up to the law, to report to the police, or to use any means to report them to the authorities. If you keep quiet, you are eligible for a certain number of years in prison if you're found guilty.
Families face this problem. Believe it or not, the moment they realize you are part of the community, they have to let you go or give you up to the authorities.
