It’s now illegal to grab/tear/burn the Israeli flag in the US. Could their control be more obvious now?

No. The case was about whether an assault was a hate crime or not.

The legal status of the flag itself is not altered. You can still burn it if you want, that’s perfectly legal. But if you burn it and then attack some Jews, the flag burning will be a factor in potentially bumping it up to a hate crime.

Burning was never actually mentioned in his case or ruling; the guy choked a woman with a flag she had around her neck. That’s the context of why “grabbing” it was bad here, OP
