Do you think this is my fault or my fathers fault?

This involves my 2nd call to police regarding abuse. He says (my father) that I was overexageraring it, especially since I couldnt have great evidence as I froze up mentally and could not recall well. So I looked like it was a prank or fake call or something. And he said if I were to ever do such a thing again, there will be consequences. And he repeated that at least for the next 5 minutes of (although he didnt directly say it) how stupid I was for it. Here's the issues of why I called- my brother has some anger issues and can get ticked off easily. And in that manner usually will either threaten or get physical and punch, slap, push or kick. He has threatened 2x before to kill me but he never recalls that. He doesnt have great memory, he says he forgets a lot of stuff. That or he lies about a lot of stuff. On top of that, about a week or 2 after the day police arrived, I was teasing my brother I'd put salt in his hair. His responce was grabbing the nearby knife, pointing it at me. And I asked him if I were to do that, would he seriously cut me? he gestured and said 'if you did that, yeah I might'. OVER SALT. AND I WASNT EVEN GOING TO DO IT. I later asked him about why he did that. He said he never did it. Im not stupid, it wasnt a dream. He lies a lot, I know thats a lie. But was this my fault or my dads?

Its not your fault at all! My brother does the same, he hasn't over salt, but he's threatened to kill me and he has bruised me with my shoe a few times, but believe me, this isn't your fault. I don't know what else to say, but I'm sorry. I hope you realize that there's no way for this to be your fault though, don't beat yourself up over it
