Sandman said that Norman's death was on the news...how didn’t Harry know that and why does he still blame Peter?

EDIT: I guess maybe Harry always heard that this was the case, but just didn’t believe it (maybe even assumed that that’s what Peter told the press)

EDIT 2: After thinking about it, I guess there are some explanations.

1. Harry himself could’ve heard that explanation countless times, but assumed that Peter was the one that said that to the press. Maybe he even thought Peter rammed the glider into Norman

2. Even if that wasn’t his assumption, Harry has always been shown to be blinded by anger (hence why he threatened MJ to get to Peter). Moreover, he probably wouldn’t want to acknowledge the truth to preserve his memory and own depiction of his father. It took someone who was basically his family to pull him out of that darkness

What do you guys think?
