Can cops threaten to press charges on you if you don't give them information on someone that has a warrant?

Yes, they certainly can, and it's not a threat! Have you ever heard of the charge of Obstructing Justice, or Harboring a Fugitive, or being an Accessory to a crime?

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.
