Prediction: if the attacker turns out to be MAGA, mainstream media and people on here won't be able to shut up about it for months. If it turns out to be #BLM/Antifa/Muslim it will be quickly buried and Don Lemon will be "but January 6th ..."
... you and your "predictions".
If it should turn out to be a black perp, there will be no shutting OAN, NewsMax or FOX up for months. If it's a furriner, they'll harp of that for years - they NEED the xenophobes.
If it's the typical white supremacist extremist, it's just yet another among literally hundreds of pending cases of white supremacist violence and will be barely a blip.
I predict - while we're predicting for free and for the record, that it is a lone wolf with very real personal and mental problems either consciously or subconsciously trying to commit suicide-by-cop, and won't even register a blip.
