Well, you’re right. But I also don’t think this was meant to be a legal declaration. It’s a political statement, it empowers his base to further incite violence against protestors.
On the other hand. while I didn't go out for this round because the nearest city to me has been very calm and mostly just black protestors saying "hey, we don't want to be murdered", at every protest I've been to since Charlottesville we've had things like church ladies bringing red-and-black cupcakes to the anarchists and aged WWII vets needing to be convinced that the black bloc kids could handle 4chan nazis and they don't need to break a hip helping. I'm not willing to predict a left turn in US politics, especially after the Democratic primary had the most depressing outcome possible, but I don't think a hard turn to the right is likely either.
Yeah, except a car did run over protestors in my city yesterday...so...
