FBI mixing in & "hate" crime is a little much.
Why? He intentionally caused the man to have a seizure - how is that not assault with a deadly weapon?
His username is "jew_goldstein" and he openly espoused his antisemitic beliefs and reasoning for causing said seizure - how is that not a hate crime?
Is the FBI is "mixing" in due to the size or scope of the case, or merely the technicalities of it? In other words, if it was only assault, the state police would take care of it. Once you start mixing in cyber, it moves to federal jurisdiction. That's not about being "a little much" - he's facing the appropriate criminal charges.
If an anti Semite knew I was a hemophiliac and gave me a paper cut, you better believe I'd want him locked up for hate crimes. Just because a Twitter gif is a new and weird sounding weapon makes it in no way harmless.
