Until last Fall we had a good relationship with our neighbors. Then suddenly in October the wife accuses my husband of killing a tree in the woods behind her house and pouring some kind of oil or liquid on her front stoop discoloring it. She called the police, they came and took a report but that was it. Since then she has verbally attacked us on several different occasions and last weekend accused my husband of pouring poison on her grass and killing it and also peeking into her kitchen window! She is in her late 60's, we know she is not stable but my question is, if she continues to make these allegations about my husband and continues to call the police can my husband be arrested just because she accuses him of something even though she cannot prove he's doing these things? And could we charge her with harrassment?
