Why did she do it?
Did anyone find out her motivation for it yet?
First off, she was insane. 90% of that I blame on liberalism the other 10% I blame on the fact that she was born in Iran.
In addition to that, she was mad because Youtube demonetized and perhaps limited her videos in other ways leading to less views, and as a result less ad revenue.
I feel sorry for her but that's no excuse to take your frustrations and failures out on innocent people. Again we find out that the police were explicitly warned about her, they found her and questioned her that morning but let her go.
