The police didn't go after you they probably hired some sort of p. I and then he posed as a cop but you can file a report to the police and then file a restraining against your parents nobody will get arrested and at this point its border like stalking and harassment.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
