You claim, “People getting arrested have helmets...” and that, “They aren’t protestors.” - here’s a video of a peaceful protestor getting taken in an unmarked vehicle [0]. Sadly, plenty more exist of similar conduct.

But two responses later and you’ve still ignored the question: what difference does it make what they’ve done - why defend unmarked police? I’ve taken the time to show evidence that it’s occurred, it’d be nice if you reciprocated some effort.
