False reports and slander.

[DizzyRose]

I really need some legal advice/help. I live in Washington state, and I have a very good reason to believe that I, and my sisters, will be the victim of a serious false police report for vandalism. The entire story, is that my mother and father recently went through a hostile divorce. My father is now living with his girlfriend and they seem to be having trouble too. His girlfriend is threatning alot of things against me and my sisters, for no real reason. We've barely even met her. I'm 18, but my sisters are both underage. 17 and 16. According to my father's girlfriend, some money went missing from her apartment recently. She blames either my father or us for doing it. Now she says she's so convinced that if anything happens to any of her things, she'll automatically say it was me and my sisters and call the police on us. She said that she could pay her friends to do "anything she wanted". Now she has left her car near our house, and has this idea about us vandalizing it. My father in a round-about way said that he believed she might try to have someone vandalize her car, then have her friends say they witnessed me and my sisters doing it. I really don't know what I can do about this. I'm afraid to call the police around here, because they would say I have no concrete proof of it.. And may contact her, in which she'd deny it and could possibly bring a harassment suit against me! I'm really frightened right now.. I can't think of anything I can do to prevent this. I don't know where else to turn. My only idea was that if she does stage this, and finger us.. I could request having a monitoring ankle bracelet placed on myself, so if she tried it again, it could be easily verified where I was. What can I do about this? Are there any lawyers or police officers who can help me..
