I have evidence but the police just dismiss it on the account I have chemo brain or just plain.

Police either dismiss on the account I have chemo brain or out right just call me crazy. A truck parked outside of my house, the guy rolled down his window and taunted me then pulled off. a car like hers followed. even though the dispatcher informed the officers their was an on going FBI investigation, they did not investigate. Also I live on a private road. Please help me speak out. These people have threatened and stalked her. she called the police but people simply called here crazy. until they finally abused her enough to go from telling me she is being stalked and threatened to saying i am doing it. these people have been planning for years and talk about having their own s3x trafficking cult and obssess over serial killers.
