To be fair, that genocide has been funded by every politician before them on both sides for generations. Israel has been sacred in America, since WW2 and then AIPAC. That doesn’t make it right, but that’s why, and it’s not going to change in one election.
Also, I’m not sure that Garland doesn’t want to appear political as much as they want the process to appear fair. This isn’t a witch hunt, they need to follow the facts and have a solid case that they can win in a court system that was made highly biased by the very person they are prosecuting. They need to win.
