Really? And if an armed thug is on their way to your house to kill you, and I know his intention and plan, and I inform the police and the mayor of your town with all the details, and they don’t give you the information so thatch you can be prepared, take action and.defend yourself - and the thug comes and kills you - wouldn’t blame fall on the authorities who had the information but chose to conceal it from you?
Of course, no disagreement.
I mearly point out that Hitler himself is said to have been 1/4 Jewish, and without Hitler's directions none of the Holocaust could happen.
