I doubt he's Jewish. He probably fancies himself a super smart Atheist. For someone calling out people for being stereotypical memes he's the epitome of a edgelord meme. He's a troll that isn't capable of staying in character. He's straight hood though.
I think you're conflating Jewel's story with someone else. He was accussed by the FBI and they tried all their shitty tactics to get him to give up his rights and confess to a crime he didn't commit. But he was never charged, the feds even released a statement acknowledging he was never formally connected to or charged with a bombing, it was a CYA move.
But he didn't kill himself he died from diabetes. He also got a public apology from Janet Reno. The FBI certainly treated him unfairly. I'm sure their methods caused some sap to self terminate but it weren't Jewell.
